Move window._opusDecoder, window._txEncoder, window._nextPlayTime
into closure-scoped variables to avoid polluting the global namespace.
Add showHint() helper to debounce status hint text, preventing
multiple button handlers from fighting over powerHint.textContent.
Throttle audio level indicator updates to max 10/sec instead of
updating on every Opus packet (~50/sec).
Hide audio controls row if the server has no audio configured
(checks /audio endpoint on load).

Add a 120-second TX safety timeout that auto-releases PTT if no mic
data flows (browser crash, disconnect). Timer resets on each audio
callback. Shows countdown in status when < 10s remaining.
Add beforeunload handler that releases PTT via navigator.sendBeacon
when the browser tab is closed during TX.
Detect WebCodecs support on page load and show "Audio requires
Chrome/Edge" on non-Chromium browsers instead of silently failing.
Remove dead playBuffer/playNode variables that were declared but
never used. Fix TX AudioData to always use mono (channel 0) with
numberOfChannels: 1 matching the f32-planar format.

Replace all hardcoded colors with CSS custom properties on :root for
easier theming. Add focus-visible outlines for keyboard accessibility.
Add mobile breakpoints for screens <= 480px.
Fix PTT button styling to use theme-aware colors (var(--accent-red))
instead of hardcoded light-theme colors (#ffefef, #f3f3f3).
Remove unused .value, .controls, and .section-title CSS classes.

Resize favicon from 1024x1024 to 64x64 and logo from 1024x1024 to
256x256, reducing total image size from ~3 MB to ~70 KB.
Fix SSE heartbeat race condition where the 10s ping interval competed
with the 8s stale threshold, causing spurious reconnects. Now pings
every 5s server-side, with a 15s stale threshold and 5s check interval
client-side.

Split the monolithic status.rs string template into three files under
assets/web/ (index.html, style.css, app.js) loaded via include_str!.
Add /style.css and /app.js endpoints with correct content types.
This makes the frontend editable with proper syntax highlighting and
linting support in editors.

Move the frontend and backend crate trees to live physically under their
respective binary crate directories, grouping related code together
without merging crate boundaries. Also flatten sub-crate nesting by
moving them out of src/ subdirectories into direct children.
