Lift the WaveformVisualizer + control popover out of the 120px NowPlayingCard box into NowPlaying as a full-panel background layer; migrate the hero-right wrapper and its scoped styles from Home into NowPlaying.
DeepDrftManager bullet now describes the public splash at / and the
catalogue move to /catalogue. Also lands a stray Phase 12 DeepDrftAPI
waveform-vault doc edit left uncommitted by a concurrent session.
Move the landed Phase 12 section from PLAN.md to COMPLETED.md; update DeepDrftAPI/Content/Public.Client CLAUDE.md for the WaveformVisualizer rename, per-track high-res datum + track-waveforms vault, track-cardinal fetch, popover controls, Ambient slot, and NowPlaying host.
Replace the 20 synthetic bars with a contained WaveformVisualizer driven by the live player, pointed at the current track; add a Fill mode (CSS-only, defaults off) sizing the canvas to its container; place the lava-lamp icon to popover on the card.
Add optional Ambient slot to ReleaseDetailScaffold (full-bleed layer behind content; absent = no regression). Cut mounts it + popover; Session mounts the engine directly behind its hero; Mix swaps its inline knob-bar for the lava-lamp popover.
Replace the TrackId-only IsActivePlayer gate with a LivePlayerTrack source that follows the playing track when it is the host track or shares the host release; single-track Mix/Session unchanged at parity.
Build WaveformVisualizerControlPopover pairing the lava-lamp trigger with the eight-knob WaveformVisualizerControls panel; style to the NowPlaying Hero look from tokens. Panel chrome scoped to the popover mount via a PanelChrome flag; Mix's inline mount unchanged.
Add GET api/track/{trackEntryKey}/waveform/high-res (+ proxy), ITrackDataService.GetTrackWaveform; rewire visualizer to resolve the current track's EntryKey and re-fetch on track change. Retire the client mix-waveform read path.
Replace the 100s default HttpClient timeout (set Timeout=Infinite) with an idle/heartbeat
deadline driven by a ProgressStreamContent wrapper that reports bytes-on-the-wire. Each tick
resets the idle window and advances a MudProgressLinear per upload row. Idle window is
configurable via Upload:IdleTimeoutSeconds (default 90s).
Per-track high-res datum keyed by EntryKey in the renamed track-waveforms vault; computed at upload for all tracks, regenerable per-track via CMS, with a re-runnable backfill. Mix read path repointed so it keeps working.
Use Fixed + RelativeWidth=Adaptive with BottomLeft/TopLeft origins to
anchor the menu under the share button; drop the inline-block shrink-wrap
container hack. Keep AutoClose off so the embed panel survives clicks.
Controls move from an inline per-page knob bar to a single popover-hosted
panel triggered by the lava-lamp icon, placed identically on every host
(Mix, Cut, Session, NowPlaying card). Dissolves the NowPlaying-controls
question — full parity via the popover. Adds the popover panel wave, panel
styling from theme tokens, and a popover-anchor open item.
