v0.0.46 — ASCII backdrop + waveform seek, floating top bar, player persistence

Added

• ASCII glyph-rain backdrop. An ambient monochrome character field is painted behind the (now translucent) panels — texture in the gutters and behind the floating top bar, softened through the cards. Settings → Appearance controls it: on/off, intensity, speed, and panel opacity (0–100, drives the --card-alpha token live). Preferences persist across restarts (beatos.appearance.v1). Respects prefers-reduced-motion (static frame) and pauses while the window is hidden/blurred.
• ASCII waveform seek bar. The player's progress bar is now a fine monochrome waveform — the track's real silhouette (peaks from the decoded buffer), bright up to the playhead, with a gentle smoothed "breathing" from the live analyser while playing. It IS the seek control (Radix click/drag preserved).
• Player remembers state across restarts. Volume, mute, shuffle, repeat, preferred role, and a resume point (last track + position) persist (beatos.player.v1). On launch the last track reloads paused at its position; if that track or its audio file is gone it falls back to idle and clears the stale pointer.
• Settings grouped into Appearance / Beats & Upload / General.

Changed

• Floating top bar (Spotify-style). The top bar's glass strip + bottom border are gone; BeatOS, back, and the centred search now float on the black canvas.
• Translucent panels over the backdrop. The three columns and single-pane routes render as translucent backlit-glass cards (.beatos-card); opacity is user-adjustable (see above).
• Collapse keeps the gutter gap and rescales the middle. Collapsing a side panel no longer removes the inter-card gap (it was supplied by the resizer element). The detail panel, when collapsed, now keeps a bordered rail with a ‹ expand chevron and a hover peek (slides in, fades a faint preview) instead of vanishing — reopen via the chevron, not only a row click.

Fixed

• Volume at minimum is now truly silent. volume = -∞ dB was not reliably honoured by the gain, leaving playback at its last level; zero now also mutes.
• A finished track keeps playing. Auto-advance paused on the next track because the engine flips to paused before emitting ended; auto-advance now forces playback (manual Next still preserves play/pause).
