Add cache-busting version query to static assets

Cloudflare was caching /static/style.css and /static/app.js at the
edge for up to 4 hours (its default Browser Cache TTL, since the app
sets no explicit Cache-Control), so deploys could look like they
hadn't landed even though the origin was already up to date. A
content hash of style.css/app.js/htmx.min.js, computed once at
startup, is now appended as ?v=<hash> to their URLs in base.html, so
every deploy that changes those files produces new, never-cached
URLs and needs no manual cache purge.

Also commits the live-sync-updates design spec, which was written
but never staged earlier in the session.

+# Live Sync Updates (HTMX) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [x]`) syntax for tracking.
+
+**Goal:** "Sync now" / "Sync all now" on the dashboard, and "Sync now" on the account page, update the affected rider row(s) or status block in place and show an auto-dismissing toast, instead of navigating to a separate result page.
+
+**Architecture:** Vendor htmx (self-hosted) as the swap mechanism. Extract the dashboard row and the account status block into reusable Jinja partials so the same markup renders both the initial page and the post-sync response. Routes always return their own primary target's current state plus zero-or-more out-of-band updates plus exactly one out-of-band toast, so every swap is safe even on a no-op path.
+
+**Tech Stack:** htmx v2.0.10 (vendored static file, no build step), plain CSS, a small addition to the existing vanilla `app.js`.
+
+**Spec:** `docs/superpowers/specs/2026-08-16-live-sync-updates-design.md`
+
+## Global Constraints
+
+- No new Python dependencies; htmx is a single vendored static JS file (spec §3).
+- `fragments/sync_result.html`, the activity retry route, and the Garmin MFA route are untouched — out of scope (spec §2).
+- Every htmx POST route returns its own primary swap target's current state (never empty) plus exactly one toast; `/sync-all` additionally returns one OOB row per outcome with a resolvable `user_id` (spec §3).
+- `POST /users/{id}/sync` and `POST /account/sync` return HTTP 200 for the "already running" case now (previously 409) — existing tests for that behavior must be updated to match, per spec §2.
+- htmx's own swap/toast behavior has no meaningful Python-level test; it is verified manually via chrome-devtools, matching how the next-sync countdown was verified (spec §4).
+
+---
+
+### Task 1: `UserRepository.dashboard_row`
+
+**Files:**
+- Modify: `app/db/repositories.py`
+- Test: `tests/db/test_repositories.py`
+
+**Interfaces:**
+- Produces: `UserRepository.dashboard_row(user_id: int) -> UserDashboardRow | None`, used by Task 4 and Task 5's routes.
+
+- [x] **Step 1: Write the failing tests**
+
+Add to `tests/db/test_repositories.py`:
+
+```python
+def test_dashboard_row_returns_row_for_known_user(user_repository) -> None:
+    user = _make_user(user_repository, "Alex")
+
+    row = user_repository.dashboard_row(user.id)
+
+    assert row is not None
+    assert row.id == user.id
+    assert row.name == "Alex"
+
+
+def test_dashboard_row_returns_none_for_unknown_user(user_repository) -> None:
+    row = user_repository.dashboard_row(999)
+
+    assert row is None
+```
+
+- [x] **Step 2: Run to verify failure**
+
+Run: `.venv/Scripts/python -m pytest tests/db/test_repositories.py -k dashboard_row -v`
+Expected: both FAIL with `AttributeError: 'UserRepository' object has no attribute 'dashboard_row'`.
+
+- [x] **Step 3: Extract the shared row builder and add `dashboard_row`**
+
+In `app/db/repositories.py`, replace the body of `dashboard_rows` with a call to a new private helper, and add `dashboard_row`:
+
+```python
+    def dashboard_rows(self) -> list[UserDashboardRow]:
+        return [self._build_dashboard_row(user) for user in self.list_all()]
+
+    def dashboard_row(self, user_id: int) -> UserDashboardRow | None:
+        user = self.get(user_id)
+        if user is None:
+            return None
+        return self._build_dashboard_row(user)
+
+    def _build_dashboard_row(self, user: SyncUser) -> UserDashboardRow:
+        last_run = self.session.scalar(
+            select(SyncRun).where(SyncRun.user_id == user.id).order_by(SyncRun.started_at.desc()).limit(1)
+        )
+        last_activity = self.session.scalar(
+            select(Activity).where(Activity.user_id == user.id).order_by(Activity.created_at.desc()).limit(1)
+        )
+        return UserDashboardRow(
+            id=user.id,
+            name=user.name,
+            enabled=user.enabled,
+            health_state=user.health_state.value,
+            action_reason=user.action_reason,
+            last_sync_at=last_run.finished_at if last_run else None,
+            last_activity_name=last_activity.activity_name if last_activity else None,
+            last_activity_status=last_activity.status.value if last_activity else None,
+        )
+```
+
+This is a pure refactor of the existing `dashboard_rows` loop body — behavior for `dashboard_rows()` itself must not change.
+
+- [x] **Step 4: Run to verify pass**
+
+Run: `.venv/Scripts/python -m pytest tests/db/test_repositories.py -v`
+Expected: all tests pass, including the two new ones and the existing `dashboard_rows`-adjacent coverage (none currently exists directly, but nothing regresses).
+
+- [x] **Step 5: Commit**
+
+```bash
+git add app/db/repositories.py tests/db/test_repositories.py
+git commit -m "Add UserRepository.dashboard_row for single-row refresh"
+```
+
+---
+
+### Task 2: Vendor htmx and wire up base.html + toast/loading CSS
+
+**Files:**
+- Create: `app/web/static/htmx.min.js` (vendored, v2.0.10)
+- Modify: `app/web/templates/base.html`
+- Modify: `app/web/static/style.css`
+- Test: none (static asset + markup/CSS; full suite re-run at the end of this task to confirm no regressions)
+
+**Interfaces:**
+- Produces: the `#toast-container` element and `.toast`/`.toast-success`/`.toast-danger`/`.toast-info` classes that Task 3 and Task 5's `fragments/toast.html` renders into; the `.htmx-request` dimming rule.
+
+- [x] **Step 1: Vendor htmx**
+
+Download `https://unpkg.com/htmx.org@2.0.10/dist/htmx.min.js` and save it verbatim as `app/web/static/htmx.min.js` (already fetched once this session — reuse that content; if re-fetching, confirm the response is the same v2.0.10 minified build before saving).
+
+- [x] **Step 2: Load htmx and add the toast container in `base.html`**
+
+```html
+    <link rel="stylesheet" href="/static/style.css">
+    <script src="/static/htmx.min.js" defer></script>
+    <script src="/static/app.js" defer></script>
+</head>
+<body>
+    <header class="topbar">
+```
+
+(only the new `htmx.min.js` line is added — `app.js` stays second so htmx's global is present before app.js's own listeners are registered, though with `defer` both run in document order regardless of load timing)
+
+And right before `</body>`:
+
+```html
+    <div id="toast-container" class="toast-container"></div>
+</body>
+```
+
+- [x] **Step 3: Add toast and htmx-request CSS to `style.css`**
+
+```css
+.toast-container {
+    position: fixed;
+    top: 1rem;
+    right: 1rem;

+### Task 3: Dashboard row and sync-all-form partials
+
+**Files:**
+- Create: `app/web/templates/fragments/user_row.html`
+- Create: `app/web/templates/fragments/sync_all_form.html`
+- Create: `app/web/templates/fragments/toast.html`
+- Modify: `app/web/templates/dashboard.html`
+- Test: `tests/web/test_dashboard_summary.py` (existing tests must keep passing — they assert on stat-tile markup, not row markup, but re-run to confirm)
+
+**Interfaces:**
+- Consumes: `UserDashboardRow` fields (spec §3), `csrf_token`.
+- Produces: `fragments/user_row.html` renders one `<li id="user-row-<id>">`, accepting `row`, `csrf_token`, `oob` (default `False`) — Task 4's route renders this same template standalone. `fragments/toast.html` accepts `message`, `level` — Task 4 and Task 5 both render it standalone.
+
+- [x] **Step 1: Create `fragments/user_row.html`**
+
+```html
+<li class="card user-card" id="user-row-{{ row.id }}"{% if oob %} hx-swap-oob="true"{% endif %}>
+    <div class="user-main">
+        <a class="user-name" href="/users/{{ row.id }}">{{ row.name }}</a>

+            <span>{{ "enabled" if row.enabled else "disabled" }}</span>
+            <span>last sync: {{ row.last_sync_at or "-" }}</span>
+            <span>last activity: {{ row.last_activity_name or "-" }} ({{ row.last_activity_status or "-" }})</span>

+```
+
+- [x] **Step 2: Create `fragments/sync_all_form.html`**

+      hx-post="/sync-all" hx-target="this" hx-swap="outerHTML" hx-disabled-elt="find button">
+    <input type="hidden" name="csrf_token" value="{{ csrf_token }}">
+    <button type="submit">Sync all now</button>
+</form>
+```
+
+- [x] **Step 3: Create `fragments/toast.html`**
+
+```html
+<div id="toast-container" hx-swap-oob="true">
+    <div class="toast toast-{{ level }}">{{ message }}</div>
+</div>
+```
+
+- [x] **Step 4: Update `dashboard.html` to use the partials**
+
+Replace the `<form ... action="/sync-all" ...>` block inside `.page-actions` with:
+
+```html
+    {% include "fragments/sync_all_form.html" %}
+```
+
+Replace the `<li class="card user-card">...</li>` block inside the `{% for row in rows %}` loop with:
+
+```html
+    {% include "fragments/user_row.html" %}
+```
+
+(the `{% else %}No users yet.{% endif %}` branch is unchanged)
+
+- [x] **Step 5: Run the full test suite**
+
+Run: `.venv/Scripts/python -m pytest tests/ -q`
+Expected: same pass count as Task 2's baseline — this is a pure template refactor (the `{% include %}` inherits `row`/`csrf_token` from the enclosing loop/page context automatically), so no existing assertion on dashboard content should break. If `tests/web/test_dashboard_summary.py` or any dashboard test fails, stop and inspect — it means the include isn't inheriting context as expected.

+
+- [x] **Step 2: Run to verify failure**
+
+Run: `.venv/Scripts/python -m pytest tests/web/test_operations.py -v`

+
+- [x] **Step 3: Rewrite the routes**
+
+In `app/web/operations.py`, add two module-level helpers near the top (after `_normalize_outcome`):
+
+```python

+
+    return HTMLResponse("".join(parts))

+### Task 6: Toast auto-dismiss and manual browser verification
+
+**Files:**
+- Modify: `app/web/static/app.js`
+- Test: none (see Global Constraints — manual verification)
+
+**Interfaces:**
+- Consumes: the `#toast-container` element (Task 2) and the `hx-swap-oob` toast fragments (Task 4, Task 5) that htmx swaps into it, firing its `htmx:oobAfterSwap` event.
+
+- [x] **Step 1: Add the auto-dismiss listener to `app.js`**
+
+Append to `app/web/static/app.js` (after the existing `DOMContentLoaded` listener, as a new top-level statement):
+
+```js
+document.body.addEventListener("htmx:oobAfterSwap", (event) => {
+    if (event.detail.target.id !== "toast-container") {

+        toast.classList.add("toast-leaving");
+        setTimeout(() => toast.remove(), 300);
+    }, 4000);
+});
+```
+
+- [x] **Step 2: Manually verify in a real browser via chrome-devtools**
+
+Start the app locally (same approach as prior manual verifications). Log in as admin, add a rider, then:
+1. Click "Sync now" on the rider's row — confirm the row updates in place (no navigation, URL stays `/`), a toast appears top-right, and it fades out and disappears after ~4 seconds.
+2. Click "Sync all now" — confirm the button re-renders, the row updates, and a summary toast appears.
+3. Log in via `/account-login` as the same rider, click "Sync now" on the account page — confirm the status block updates in place and a toast appears.
+4. Check the DevTools console (`list_console_messages`) for errors after each of the above.
+5. Take a screenshot showing a toast visible on the dashboard.
+
+Expected: no full-page navigation for any of the three actions, no console errors, toast appears and later disappears.

+# Visual Redesign ("Ride Computer" Dark Theme) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [x]`) syntax for tracking.
+
+**Goal:** Replace the app's light, generic look with a distinctive dark "bike computer cockpit" theme, and evolve the existing next-sync timestamp into a live ticking countdown, without changing any Python route, model, or template markup.
+
+**Architecture:** A CSS design-token rewrite in `app/web/static/style.css` (color, typography, motion) that every existing template already picks up through shared classes (`.card`, `.badge`, `button`/`.btn`, `table`, `form.stacked-form`, `.sync-status`) — no template edits required. Separately, `app/web/static/app.js` gains a client-side countdown that ticks the already-rendered `time.next-sync[data-utc]` element down to zero, replacing the one-time UTC→local formatting it does today.
+
+**Tech Stack:** Plain CSS custom properties, vanilla JS (no new dependencies, no build step — matches the existing project convention of zero frontend tooling).
+
+**Spec:** `docs/superpowers/specs/2026-08-16-visual-redesign-design.md`
+
+## Global Constraints
+
+- No new dependencies, no build step — plain CSS and vanilla JS only (spec §2, §3).
+- No route, model, or Python business-logic changes (spec §1).
+- No template markup changes — every template already consumes the shared classes this plan restyles (spec §2, §6). `base.html`'s `.topbar-right` / `.sync-status` / `time.next-sync[data-utc]` structure from the prior next-sync feature is reused as-is.
+- Dark theme only — no light-mode toggle (spec §2 "Out of scope").
+- `data-utc` stays the server↔client contract; `tests/web/test_next_sync_display.py` must keep passing unmodified (spec §4 point 5).
+- `base.html` needs **no edits** in this plan: the `.topbar-right` wrapper, the `.sync-status` span, and the `time.next-sync[data-utc]` element it needs already exist from the earlier next-sync feature. The spec's §6 rollout mentions `base.html` as a file touched by this work; in practice the existing markup already satisfies every hook Task 1's CSS and Task 2's JS need, so no template diff is required — this is a positive scope reduction, not a gap.
+- CSS token value changes and the countdown's visual behavior have **no meaningful automated test** — the user explicitly chose manual/browser verification (via chrome-devtools screenshots) over introducing a JS test runner for this work. This is a deliberate, human-approved exception to normal TDD practice for these two tasks specifically; it does not extend to any future task that adds real branching logic without the user's sign-off.

+
+### Task 1: Dark cockpit color, typography, and component tokens
+
+**Files:**
+- Modify: `app/web/static/style.css` (complete rewrite — every rule below)
+- Test: none (pure CSS token values — see Global Constraints)
+
+**Interfaces:**
+- Consumes: nothing (leaf task, no code dependencies from other tasks).
+- Produces: the `--bg`, `--surface`, `--surface-raised`, `--border`, `--text`, `--text-muted`, `--accent`, `--danger`, `--danger-bg`, `--success`, `--success-bg`, `--warning`, `--warning-bg`, `--neutral`, `--neutral-bg`, `--info`, `--info-bg`, `--radius`, `--shadow`, `--mono` custom properties and the `.sync-status` / `.sync-status .next-sync` selectors that Task 2's markup (already shipped in `base.html`) relies on for its visual presentation.
+
+- [x] **Step 1: Replace `app/web/static/style.css` with the new token system and components**

+```
+
+Notes on deliberate deviations from a literal reading of the spec, decided during implementation for consistency and to avoid template edits:
+- `table td` and `dl.info-grid dd` get monospace/tabular-nums globally (not just "stats" cells) since every table and info-grid in this app is already timestamp/count/state data, and templates aren't being touched to add per-cell classes. Badges inherit this too (they sit inside `td`), which reads like an instrument-panel status readout rather than a problem.
+- `--primary`/`--primary-hover` are removed (replaced by `--info` for links and `--accent` for buttons) since nothing in the templates references them directly (verified via grep — no inline `style="var(--...)"` usage anywhere).
+- Button hover uses `filter: brightness(0.88)` instead of a second hardcoded accent hex, keeping the palette to the named tokens in the spec.
+
+- [x] **Step 2: Run the full test suite to confirm no regressions**
+
+Run: `.venv/Scripts/python -m pytest tests/ -q`
+Expected: same pass count as before this change (202 passed; the pre-existing unrelated `tests/mywhoosh/test_tokenstore.py::test_tokenstore_round_trip_and_permissions` failure on Windows is expected and untouched by this task).
+
+- [x] **Step 3: Commit**
+
+```bash
+git add app/web/static/style.css
+git commit -m "Redesign UI with dark cockpit color and typography tokens"
+```
+
+---
+
+### Task 2: Live-ticking sync countdown
+
+**Files:**
+- Modify: `app/web/static/app.js` (complete rewrite)
+- Test: none (see Global Constraints — user chose manual verification over introducing a JS test runner)
+
+**Interfaces:**
+- Consumes: the `time.next-sync[data-utc="<ISO-8601 instant>"]` element already rendered by `base.html` (from the previously shipped next-sync feature) and the `.sync-status` / `.sync-status .next-sync` CSS from Task 1.
+- Produces: nothing consumed by a later task — this is the last code task.
+
+- [x] **Step 1: Replace `app/web/static/app.js` with the countdown implementation**
+
+```js
+function formatCountdown(remainingMs) {
+    if (remainingMs <= 0) {
+        return "due now";
+    }
+    const totalSeconds = Math.floor(remainingMs / 1000);
+    const hours = Math.floor(totalSeconds / 3600);
+    const minutes = Math.floor((totalSeconds % 3600) / 60);
+    const seconds = totalSeconds % 60;
+    const pad = (n) => String(n).padStart(2, "0");
+    if (hours > 0) {
+        return `${pad(hours)}:${pad(minutes)}:${pad(seconds)}`;
+    }
+    return `${pad(minutes)}:${pad(seconds)}`;
+}
+
+function startSyncCountdown(el) {
+    const target = new Date(el.dataset.utc);
+    if (Number.isNaN(target.getTime())) {
+        return;
+    }
+    el.title = `${target.toLocaleString(undefined, { dateStyle: "medium", timeStyle: "short" })} · ${el.dataset.utc} UTC`;
+
+    let intervalId = null;
+    const tick = () => {
+        const remaining = target.getTime() - Date.now();
+        el.textContent = formatCountdown(remaining);
+        if (remaining <= 0 && intervalId !== null) {
+            clearInterval(intervalId);
+        }
+    };
+    tick();
+    if (target.getTime() - Date.now() > 0) {
+        intervalId = setInterval(tick, 1000);
+    }
+}
+
+document.addEventListener("DOMContentLoaded", () => {
+    document.querySelectorAll("time.next-sync[data-utc]").forEach(startSyncCountdown);
+});
+```
+
+Why `intervalId` is declared with `let` before `tick` runs once synchronously: the first `tick()` call happens before `setInterval` returns, so if the target is already due on page load, `tick` must not call `clearInterval` on a not-yet-assigned `const` — that would throw a `ReferenceError`. Declaring `intervalId` as `let intervalId = null` up front and only scheduling the interval at all when the target is still in the future avoids the bug entirely (an already-due countdown just renders "due now" once and never starts ticking).
+
+- [x] **Step 2: Manually verify in a real browser via chrome-devtools**
+
+Start the app locally (same approach as the next-sync feature verification: temp SQLite DB, a valid `CREDENTIAL_ENCRYPTION_KEY` from `Fernet.generate_key()`, `ADMIN_PASSWORD`/`SECRET_KEY` set, `uvicorn app.main:create_app --factory`), then:
+1. Navigate to `/login` and confirm the countdown ticks down every second (e.g. `04:58` → `04:57`).
+2. Navigate to `/` (dashboard, after admin login) and confirm the same ticking countdown appears there too.
+3. Edge case: temporarily set the fake/real scheduler's `next_tick` to a timestamp in the past (or wait past it) and reload — confirm the element shows `due now` instead of a negative or malformed countdown, and confirm no JS error appears in the DevTools console (`list_console_messages`).
+4. Take a screenshot of the dashboard and the login page to visually confirm Task 1's dark theme and Task 2's countdown render together correctly.
+
+Expected: countdown ticks live, "due now" renders cleanly for an already-past target, no console errors, screenshots show the dark cockpit theme with the lime countdown readout in the topbar.
+
+- [x] **Step 3: Commit**
+
+```bash
+git add app/web/static/app.js
+git commit -m "Turn the next-sync indicator into a live ticking countdown"
+```
+
+---
+
+### Task 3: Final full-suite regression check
+
+**Files:**
+- None modified — verification only.
+
+**Interfaces:**
+- Consumes: the completed state of Task 1 and Task 2.
+- Produces: nothing (terminal task).
+
+- [x] **Step 1: Run the full Python test suite**
+
+Run: `.venv/Scripts/python -m pytest tests/ -q`
+Expected: 202 passed, 1 pre-existing unrelated failure (`test_tokenstore_round_trip_and_permissions`, a Windows file-permission-bits issue predating this plan) — identical to the baseline recorded in Task 1 Step 2.
+
+- [x] **Step 2: Report completion to the user**
+
+Summarize what changed (dark cockpit theme across every page via shared CSS classes, live-ticking sync countdown) and point at the two screenshots taken in Task 2 Step 2 as evidence.

+# Live Sync Updates (HTMX) — Design
+
+Date: 2026-08-16
+Status: Draft for user review
+
+## 1. Goal
+
+Replace the full-page navigation that currently happens after clicking
+"Sync now" / "Sync all now" with an in-place update: the affected rider
+row(s) refresh with their new status, and a short toast reports the
+outcome — without leaving the dashboard or account page.
+
+## 2. Scope
+
+### In scope
+
+- Vendoring htmx (v2.0.10, self-hosted, no CDN) as the swap mechanism.
+- Dashboard: per-rider "Sync now" and "Sync all now".
+- Account page (self-service): "Sync now".
+- A toast notification system (one at a time, auto-dismissing) built on
+  htmx out-of-band swaps.
+- Removing the HTTP 409 special case for "sync already running" — it
+  becomes a normal toast instead of a distinct error page/status.
+
+### Out of scope (unchanged in this pass)
+
+- Activity retry button (`/activities/{id}/retry`) — still navigates to
+  the old `fragments/sync_result.html` page.
+- Garmin MFA form (`/users/{id}/garmin-mfa`) — still navigates to the old
+  page; MFA failure often needs a fresh code anyway, so the extra step is
+  less costly there.
+- Live-updating the "Recent sync runs" table on the account/user detail
+  pages — a completed sync's new row only appears after the next full
+  page load.
+- Any change to `SyncManager`, `SyncOutcome`, or scheduler behavior.
+
+## 3. Architecture
+
+### htmx
+
+`app/web/static/htmx.min.js` (vendored, v2.0.10) is loaded in `base.html`
+via `<script src="/static/htmx.min.js" defer></script>`, alongside the
+existing `app.js`.
+
+### The "always return current state" rule
+
+Every htmx-driven POST route in scope returns two things in one response
+body:
+
+1. The current, freshly-reloaded state of its own primary swap target
+   (even on a no-op path like "sync already running", or on the
+   `/sync-all` form itself, which always re-renders unchanged). This
+   makes every swap safe/idempotent — the target is never replaced with
+   nothing.
+2. Exactly one out-of-band toast fragment (`fragments/toast.html`,
+   `hx-swap-oob="true"` on `#toast-container`) describing what happened.
+
+`/sync-all` additionally emits one out-of-band row update
+(`fragments/user_row.html` rendered with `oob=True`) per rider whose
+outcome carries a known `user_id` — riders unaffected by that run (e.g.
+disabled) are left alone.
+
+### Shared row partial
+
+`app/web/templates/fragments/user_row.html` renders one
+`<li class="card user-card" id="user-row-{{ row.id }}">...</li>`, taking
+`row` (a `UserDashboardRow`), `csrf_token`, and `oob` (default `False`,
+adds `hx-swap-oob="true"` to the root element when `True`). `dashboard.html`
+`{% include %}`s it once per row in its existing loop (`oob` omitted,
+defaults to `False`) instead of inlining the `<li>` markup — this is the
+only change to the existing loop, so the initial page render is
+byte-for-byte equivalent to today's markup plus the new `hx-*` attributes
+on the row and its form.
+
+### Shared account status partial
+
+`app/web/templates/fragments/account_status.html` renders the
+`<dl class="info-grid" id="account-status">...</dl>` block (Status,
+MyWhoosh state, Garmin state, Action reason) that today lives inline in
+`account/detail.html`. Same include pattern.
+
+### New repository method
+
+`UserRepository.dashboard_row(user_id: int) -> UserDashboardRow | None`
+in `app/db/repositories.py` — the existing `dashboard_rows()` loop body is
+extracted into a private `_build_dashboard_row(user: SyncUser) -> UserDashboardRow`
+helper that both `dashboard_rows()` and the new `dashboard_row(user_id)`
+call, so there is exactly one place that assembles a row.
+
+### Route changes
+
+`app/web/operations.py`:
+
+- `manual_sync` (`POST /users/{user_id}/sync`): on success, on
+  `SyncAlreadyRunning`, and on any other outcome, always ends by opening a
+  fresh session, calling `UserRepository(session).dashboard_row(user_id)`,
+  and rendering `fragments/user_row.html` (`oob=False`, since this row IS
+  the primary `hx-target`) followed by a toast whose message/level depend
+  on the outcome. Always returns HTTP 200 now (no more 409).
+- `manual_sync_all` (`POST /sync-all`): re-renders the trigering `<form>`
+  unchanged as the primary swap content (`fragments/sync_all_form.html`,
+  a two-line partial holding just that form), then one
+  `fragments/user_row.html` (`oob=True`) per outcome with a resolvable
+  `user_id`, then one summary toast, e.g. `"Synced 3 riders — 2 ok, 1
+  failed"` or `"No riders to sync"` when the outcome list is empty.
+
+`app/web/account.py`:
+
+- `account_sync` (`POST /account/sync`): same "always return current
+  state + toast" shape, but the primary target is
+  `fragments/account_status.html` re-rendered from the freshly reloaded
+  `SyncUser`, not a row.
+
+### Toast levels and copy
+
+| Situation | Level | Message |
+|---|---|---|
+| `status in (success, partial)` | success | `"<name>: <imported> imported, <failed> failed"` |
+| `status == failed` | danger | `"<name>: sync failed — <message or 'unknown error'>"` |
+| `SyncAlreadyRunning` caught | info | `"<name>: sync already running"` |
+| Exception (unexpected) | danger | `"<name>: sync error — <message>"` |
+| `/sync-all` summary | success if all ok else danger | `"Synced <n> riders — <ok> ok, <failed> failed"` |
+| `/sync-all` with zero enabled riders | info | `"No riders to sync"` |
+
+`fragments/toast.html` takes `message: str` and `level: Literal["success",
+"danger", "info"]`, rendering:
+
+```html
+<div id="toast-container" hx-swap-oob="true">
+    <div class="toast toast-{{ level }}">{{ message }}</div>
+</div>
+```
+
+`base.html` gets an empty `<div id="toast-container" class="toast-container"></div>`
+right before `</body>` so the very first toast has something to swap.
+
+### Auto-dismiss
+
+`app/web/static/app.js` gains an `htmx:oobAfterSwap` listener: when the
+swapped element's id is `toast-container`, it schedules the `.toast`
+child's removal after 4 seconds via a CSS class (`toast-leaving`, an
+opacity/transform transition) added 300ms before the actual `remove()`
+call, so it fades rather than disappearing instantly.
+`prefers-reduced-motion: reduce` disables the CSS transition (the toast
+still disappears at the same 4-second mark, just without animating).
+
+### CSS
+
+New `.toast-container` (fixed, top-right, stacked via flex column though
+only one toast exists at a time), `.toast`, `.toast-success`,
+`.toast-danger`, `.toast-info` rules using the existing color tokens
+(`--success`/`--danger`/`--info` text on `--surface-raised` background,
+consistent with the existing badge treatment). Existing
+`button.htmx-request` / `.btn.htmx-request` rule dims the control
+(`opacity: 0.6`) while a request is in flight — htmx adds/removes this
+class automatically, no JS needed.
+
+## 4. Testing
+
+- `UserRepository.dashboard_row` — unit tests mirroring `dashboard_rows()`
+  coverage (found user returns expected fields, unknown id returns
+  `None`) in `tests/db/test_repositories.py`.
+- Route-level tests (`tests/web/test_operations.py`,
+  `tests/web/test_account_web.py` or a new
+  `tests/web/test_live_sync_updates.py`) using the existing `TestClient` +
+  `fake_sync_manager` fixture, asserting on the returned HTML: the row's
+  `id="user-row-<id>"` element is present with updated fields, a
+  `hx-swap-oob="true"` toast div is present with the expected message
+  class, `/sync-all` emits one OOB row per outcome, and the
+  already-running path returns HTTP 200 (not 409) with an info toast.
+- No htmx JS itself is unit-testable from Python; the actual in-browser
+  swap behavior (row updates without navigation, toast appears and
+  disappears) is verified manually via chrome-devtools, the same way the
+  next-sync countdown was verified.
+
+## 5. Rollout
+
+Files touched: `app/web/static/htmx.min.js` (new, vendored),
+`app/web/static/app.js`, `app/web/static/style.css`, `app/web/templates/base.html`,
+`app/web/templates/dashboard.html`, `app/web/templates/account/detail.html`,

+`app/web/templates/fragments/sync_all_form.html` (new),
+`app/db/repositories.py`, `app/web/operations.py`, `app/web/account.py`.
+`fragments/sync_result.html` is untouched (still used by retry/MFA,
+out of scope).

+# Visual Redesign — "Ride Computer" Dark Theme — Design
+
+Date: 2026-08-16
+Status: Draft for user review
+
+## 1. Goal
+
+Replace the current light, generic admin-template look with a distinctive dark
+"bike computer cockpit" theme grounded in the app's own subject matter (indoor
+cycling sync, Garmin telemetry). The redesign is a shared foundation: it must
+land before the planned dashboard summary tiles and live-update UX polish, so
+those can be built directly in the new visual language instead of needing a
+second pass.
+
+This spec covers only the visual system and the already-shipped next-sync
+indicator's evolution into a live countdown. It does not add new pages, new
+data, or new business logic.
+
+## 2. Scope
+
+### In scope
+
+- New CSS design-token system (color, spacing reuse, borders) replacing the
+  current light theme in `app/web/static/style.css`.
+- Cockpit-style topbar (dark, brand mark, nav, live sync countdown).
+- Restyled shared components: cards, buttons, badges, tables, forms, empty
+  states — applied globally via shared CSS classes so every existing template
+  (login, account-login, dashboard, account detail/edit, users
+  detail/new/edit, system, sync result fragment) picks it up without
+  structural rewrites.
+- Typographic treatment: uppercase tracked labels for headings/section labels
+  (extends the existing table-header pattern), tabular monospace numerals for
+  all stats/timestamps/counters.
+- Evolving the existing static next-sync timestamp (`app/web/static/app.js`,
+  `base.html`) into a live, client-ticking countdown.
+- Accessible focus states (visible lime outline) and `prefers-reduced-motion`
+  handling for the one animated element (the countdown) and card entrance.
+
+### Out of scope (separate follow-up specs)
+
+- Dashboard summary/stat tiles (next phase, builds on this theme).
+- Live sync results without full page reload (UX-polish phase).
+- Any light-mode / theme-toggle support (explicitly rejected by user — dark
+  only).
+- New charts/statistics views.
+- Any change to routes, models, or sync/business logic.
+
+## 3. Design tokens
+
+### Color
+
+| Token | Hex | Usage |
+|---|---|---|
+| `--bg` | `#12151A` | Page background |
+| `--surface` | `#1A1F27` | Cards, topbar, table zebra-free rows |
+| `--surface-raised` | `#232935` | Hover states, inputs |
+| `--border` | `#2A3038` | Hairline dividers/card borders |
+| `--text` | `#E7EAF0` | Primary text |
+| `--text-muted` | `#8B93A3` | Secondary text, labels, hints |
+| `--accent` | `#C8FF4D` | Electric lime — signature countdown, primary buttons, focus rings, "healthy" status |
+
+Semantic status colors (each with a ~14% opacity tint of the same hue over
+`--surface` for badge backgrounds, matching the existing `--*-bg` variable
+pattern already in `style.css`):
+
+| State | Hex | Meaning |
+|---|---|---|
+| Success / healthy | `--accent` `#C8FF4D` | Reuses the signature accent — a healthy sync *is* the good state the accent celebrates |
+| Warning / degraded | `#FFB454` | Amber |
+| Danger / action required / failed | `#FF5F6D` | Coral |
+| Info / syncing / running | `#5FD4FF` | Cyan |
+| Neutral / disabled | `#5A6472` | Slate |
+
+These map 1:1 onto the existing `--success`, `--warning`, `--danger`,
+`--info`, `--neutral` variable names already used by `.badge-*` classes in
+`style.css` — only their values change, not the class structure, so templates
+need no edits for badges.
+
+### Typography
+
+- Body/UI face: unchanged system stack (`-apple-system, BlinkMacSystemFont,
+  "Segoe UI", Roboto, Helvetica, Arial, sans-serif`) — no new font loads,
+  works offline in a self-hosted container.
+- Monospace face for all numeric data (stats, timestamps, the countdown,
+  table numeric columns): `ui-monospace, SFMono-Regular, Menlo, Consolas,
+  "Liberation Mono", monospace`, with `font-variant-numeric: tabular-nums`.
+- Headings and structural labels (`h1`/`h2`, `.badge`, table `th`, the new
+  topbar labels): uppercase, `letter-spacing: 0.06em`, extending the tracked
+  uppercase style `table th` already has today — applied consistently instead
+  of only in tables.
+
+### Layout
+
+- Topbar becomes the cockpit header: `--surface` background, hairline bottom
+  border, brand mark left, nav + live countdown grouped right (existing
+  `.topbar-right` wrapper from the next-sync work is reused).
+- Cards: hairline `--border` outline, `--surface` background, no drop shadow
+  (shadows read poorly on dark; hairlines carry the "device bezel" feel
+  instead). Radius stays at the existing `--radius: 10px`, unchanged.
+- Buttons: primary uses `--accent` background with dark text (for contrast
+  against the light lime); secondary keeps outline/ghost style against
+  `--surface`.
+- Focus-visible: 2px `--accent` outline on all interactive elements (links,
+  buttons, inputs) — dark backgrounds need this to stay accessible since the
+  current subtle browser default focus ring is hard to see on `--surface`.
+
+### Motion
+
+- The live countdown ticks once per second (text content update only, no
+  layout shift).
+- Cards fade/slide in ~150ms on initial page load, `translateY(4px) → 0`.
+- Both respect `prefers-reduced-motion: reduce` (countdown text still updates,
+  since it's informational, not decorative; the card entrance animation is
+  skipped entirely).
+
+## 4. Signature element: live sync countdown
+
+`app/web/static/app.js` currently does a one-time UTC→local conversion of the
+`time[data-utc]` element on `DOMContentLoaded`. It's extended to:
+
+1. On load, read `data-utc` as the target instant.
+2. If the target is in the future, start a `setInterval` (1s) that computes
+   the remaining duration and renders it as `HH:MM:SS` (or `MM:SS` under an
+   hour) in monospace, e.g. `NEXT SYNC ▸ 00:12:04`.
+3. If the target is in the past (page left open past the sync time, or
+   `next_tick` not yet known on first boot), render `due now` instead of a
+   negative countdown.
+4. The `title` attribute keeps showing the absolute local time (via
+   `toLocaleString()`) and the original UTC instant, so hovering still gives
+   an absolute reference — this preserves today's behavior as a fallback/aid.
+5. `data-utc` stays the templating contract between server and client (same
+   attribute the current tests assert on), so no server-side route or test
+   changes are needed for this evolution — only `app.js` behavior and the
+   surrounding CSS/markup in `base.html` change.
+
+No server-side change: `next_sync_tick()` in `app/web/routes.py` and the
+`base.html` template variable wiring stay as they are; only the visual
+presentation and `app.js` ticking logic change.
+
+## 5. Testing
+
+This is a CSS/JS-presentation change with one markup adjustment (countdown
+wrapper element/label in `base.html`). Existing server-rendered tests assert
+on `data-utc="..."` substrings and text content, not on CSS classes or exact
+visual output, so no test breakage is expected. No new automated test is
+meaningful for pure CSS token values; the existing
+`tests/web/test_next_sync_display.py` continues to guard the server-side
+contract (the attribute and value), and manual verification (screenshot) is
+used to confirm the visual outcome, consistent with how the next-sync feature
+was verified.
+
+## 6. Rollout
+
+Single pass across `style.css`, `base.html`, `app.js`. No template
+restructuring needed beyond `base.html`'s topbar, since all other templates
+already consume the shared `.card`, `.badge`, `button`/`.btn`, `table`, and
+`form.stacked-form` classes this spec restyles centrally.
