- `WaveformVisualizerControlPopover.razor`: Pairs the lava-lamp icon button with `WaveformVisualizerControls` as `MudPopover` overlay content. This is the unit every host places — one icon anywhere gives the full eight-knob panel on demand. Styled to the NowPlaying Hero look from `deepdrft-tokens.css` (no hardcoded hex). Placed identically on Mix, Cut, Session, and the NowPlaying hero panel (full parity; in NowPlaying it sits in `.np-visualizer-controls` at the panel's top-right corner, not inside `NowPlayingCard`).
- `WaveformZoomMapping.cs`: Maps the `WaveformVisualizerControlState.Resolution` fraction to an integer zoom level for the WebGL renderer.
- `NowPlayingCard.razor`: Home-page text panel showing the currently playing track (label, title, sub-line). Renders label/"Now Playing" dot, track name, and artist·release sub-line from the cascaded `IStreamingPlayerService`. Subscribes to `IPlayerService.StateChanged` in `OnParametersSet` (reference-guarded, idempotent) and unsubscribes on dispose to re-render on track/state change. No visualizer or popover; those moved to `NowPlaying.razor`.
- `NowPlaying.razor`: Owns the home hero's right-side panel (`.now-playing-panel` — the outer wrapper formerly called `.hero-right` in `Home.razor`). Mounts `<WaveformVisualizer Fill="true">` as a full-bleed background inside `.np-visualizer-bg`, `<WaveformVisualizerControlPopover>` in `.np-visualizer-controls` (top-right corner), the three pulsing `.circle-deco` rings, and the content layer (hosts `<NowPlayingCard>` + `<NowPlayingStats>`). `Home.razor`'s `MudItem` renders `<NowPlaying />` directly with no wrapper.
- `NowPlaying.razor`: Owns the home hero's right-side panel (`.now-playing-panel` — the outer wrapper formerly called `.hero-right` in `Home.razor`). Mounts `<WaveformVisualizer Fill="true">` as a full-bleed background inside `.np-visualizer-bg`, `<WaveformVisualizerControlPopover>` in `.np-visualizer-controls` (top-right corner), the three pulsing `.circle-deco` rings, and the content layer (hosts `<NowPlayingCard>` + `<NowPlayingStats>`). `Home.razor`'s `MudItem` renders `<NowPlaying />` directly with no wrapper. Subscribes to `IPlayerService.StateChanged` in `OnParametersSet` (reference-guarded, idempotent) and unsubscribes on dispose — needed because the player cascade is `IsFixed` (the provider's own re-render does not reach `NowPlaying`), so the subscription is the only way to re-render and re-propagate `ReleaseEntryKey`/`TrackId`/`TrackEntryKey` into `<WaveformVisualizer>` when the playing track changes.
- `ReleaseDetailScaffold.razor`: Shared scaffold for release detail pages. Gained an optional `Ambient` `RenderFragment` slot (Phase 12) — a full-bleed layer rendered behind the main content. Absent slot = no regression. Cut mounts `<WaveformVisualizer>` + `<WaveformVisualizerControlPopover>` here; Mix uses its own full-bleed mount outside the scaffold.
- `Helpers/`: Utilities and mapper functions.
- `PlaybackIcons.cs`: Static `Resolve(isPlaying, isPaused, trackId, currentTrackId)` method — the sole glyph-mapping source for transport icons across all surfaces. Returns `(Icon, IsActive, IsPaused)` tuple.
