- Move colophon (credit/email/source link) from sticky footer into
a dedicated About dialog, opened from a new header button
- Drop ~64px of bottom container padding now that the footer is gone
- Loosen vinyl-stage aspect-ratio (1:1 -> 1:0.85) so the disc no
longer leaves a tall empty band below the sleeve
- Switch tonearm height: 36% to aspect-ratio: 1 to keep proportions
consistent across the new stage ratio
- Add about.* / dialog.close i18n keys for EN and RU
- Add vinyl-variants-mockup.html as next design reference target
Frontend hot path (player.js, background.js):
- visualizer rAF: drop per-frame getComputedStyle('--accent') (cached on
applyAccentColor), build canvas LinearGradient once per accent change
instead of 32× per frame, batch all bars into a single beginPath/fill
- FPS-gate canvas redraw via frequencyDataVersion so 60-144 Hz monitors
stop re-rendering identical frames produced at 30 Hz on the backend
- editorial spectrum bars: replace style.height (layout) with
transform: scaleY (compositor-only); cache bar refs, pre-compute
per-bar gain/range, dedup writes at 1/1000 quantization
- coalesce VU needle into the visualizer rAF; cache vuNeedle ref;
dedup angle writes at 0.1°
- updateUI: status-payload fingerprint short-circuits the redundant
status_update broadcasts that fire during a track change
- swapArtworkSrc: only force layout reflow when keyframe is in flight;
drop the ?_=Date.now() cache-buster so identical artwork URLs reuse
the decoded bitmap; mini/glow imgs only re-set src when changed
- drop the fullscreen MutationObserver — fs-bloom-art is mirrored
directly from the artwork-swap path, eliminating the second blur paint
- updateProgress: skip text writes when the rounded second hasn't moved;
POSITION_INTERPOLATION_MS 100 → 250
- background.js: lift resizeBackgroundCanvas out of the rAF body, cache
step, accept new int-scaled wire format
CSS:
- spectrum bars use transform: scaleY(var(--bar-h-scale)) + transition
on transform; will-change updated to transform
- album-art-glow and fs-bloom-art switched to small-source-blur trick
(render at 20-25% size, scale 4-6×, lower blur radius) — visually
equivalent, ~10-25× cheaper repaint on track change
- drop unused transition: filter on .vinyl-stage #album-art
Backend (audio_analyzer.py, websocket_manager.py):
- pre-allocate windowed and cumsum buffers; replace
np.concatenate(([0.0], np.cumsum(...))) with cumsum[0]=0 +
np.cumsum(out=cumsum[1:]); float32 hanning window
- RMS via np.dot(mono, mono) — no astype copy, no ** temp
- int16 wire format (scale=1000) — smaller JSON, no Python float boxing
- versioned data + threading.Event so _audio_broadcast_loop is event-
driven (ev.wait + monotonic seq dedup) instead of polling on a timer
with the always-false `data is _last_data` identity check
ruff clean, pytest 7 passed / 3 numpy-skipped, esbuild bundle 113.6 kB.
Restructures the player tab DOM to actually look like the editorial
mockup, not just inherit new fonts. The previous commit only swapped
tokens & typography on the legacy Spotify-clone layout.
DOM additions (all preserve existing JS-touched IDs):
- Vinyl stage: rotating vinyl wrapping the existing #album-art as a
circular center label; spins only when state=playing via CSS hook
- SVG tonearm: pivots in/out based on data-playstate
- Kicker line: copper italic mono header above the track title
- Editorial 4-cell metadata grid: State / Source / Elapsed / Length
- Decorative spectrum bars (30, CSS-only animation, paused when idle)
- VU meter cluster: needle visual driven by volume %, alongside the
preserved volume slider for a11y
- Folio marks: top-left and top-right of the player container
JS hooks (small, additive):
- updatePlaybackState now sets :root[data-playstate] for CSS
- progress tick mirrors timecode into meta-grid cells
- volume update rotates the VU needle
- folio-version mirrors the version label
i18n:
- new keys: player.kicker, player.modes, player.folio_*, meta.*
- added to both en.json and ru.json
Restored: media_server/static/redesign-mockup.html (Studio Reference
visual reference; deleting it in the prior commit was a mistake).
- Abstract ReleaseProvider protocol for platform-agnostic version checking
- GiteaReleaseProvider implementation using stdlib urllib
- UpdateChecker service with periodic background checks and WS broadcast
- Persistent dismissible banner in Web UI when a new version is detected
- Health endpoint now returns cached update info
- Configurable via update_check_enabled and update_check_interval settings
- i18n support (EN/RU)
When no api_tokens are configured (the new default), all endpoints
are accessible without authentication. The frontend detects this
via /api/health's auth_required field and skips the login form.
- Backend: auth.py skips verification when api_tokens is empty
- Frontend: shared getAuthHeaders()/hasCredentials() helpers replace
scattered token logic across all JS modules
- Health endpoint exposes auth_required for frontend discovery
- config.example.yaml ships with tokens commented out
- CLI --show-token and startup log reflect disabled state
