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

visual reference; deleting it in the prior commit was a mistake).
