MixBrowser WaveformCell: wrap icon+button in MudStack Row. SessionBrowser
HeroCell: split into two SpecialActionColumns (thumb + button). AlbumBrowser
track table: always show regenerate button for Profile and High-res.
Move Phase 15 from PLAN to COMPLETED; fix DDIcons location to
DeepDrftShared.Client/Common; update WaveformVisualizerControls/Popover/State
descriptions for the three-row modal-overlay rework.
Tokenize scrim navy RGB triple (--deepdrft-scrim-rgb); LAVA row now
flex-start so knobs group left; WAVE row keeps space-between for
right-pinned width knob; remove inert margin-left:auto/wvc-row-right;
correct stale seven->ten count in OnControlStateChanged comment.
New shared ReleaseDescription control renders the blurb in a uniform themed block
below the hero/header; null/whitespace renders nothing, with no layout artifact.
Retire the Tracks list view; promote the Releases view to /releases with
medium tabs (ALL/CUTS/SESSIONS/MIXES). Migrate bulk profile/high-res
backfill and per-track waveform columns into the releases grids. Point
catalogue cards at the three mediums. Remove dead BrowseMode/ViewModel.
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).
