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.
Daniel resolved the open questions: high-res compute for all media (B); the
waveform datum is per-track, not per-release (release is just the host —
dissolves the multi-track-Cut question); full-parity lava controls on all
detail hosts. Splits 12.B into compute+backfill / fetch+bridge; renames the
scaffold slot to Ambient. NowPlaying-card controls left as open sub-question.
Generalize the Mix-only WebGL lava visualizer into one release-cardinal
WaveformVisualizer serving Mix detail, all Release Detail pages, and the
home NowPlaying card. Four waves; flags the non-Mix datum-resolution call.
Smooth the loudness contour (~50 ms envelope at preprocessing + decode-time, plus
smootherstep render reconstruction); retune wax↔waveform collision to bouncy/sub-unity
(no explosion/stuck/jitter); split the bubbles knob into fluid-amount + fluid-viscosity
(cohesion via uniform-only smin/wobble); retune scroll/gravity/heat/width ranges; make
the colour rotation visible and boost OKLab chroma; the controls bar now holds its
layout and hides only its knobs via a Visible parameter.
