# 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**

Replace the entire file content with:

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.
