### Phase 20 — Wave 2 — Theater Mode refinements (landed 2026-06-21)
|
||||
|
||||
**Landed:** 2026-06-21 on dev.
|
||||
|
||||
- **What:** Three refinements to the base Phase 20 feature. (1) **Full-screen detail body:** each detail page's foreground container gained `.dd-detail-fill` (`min-height: calc(100vh - var(--deepdrft-nav-height, 88px))`), so the visualizer reads as full-screen and the footer is pushed below the fold regardless of Theater Mode. (2) **Eased collapse (no pop):** the hard `@if` content-hide on the three detail pages was replaced by a `.dd-theater-collapsible` / `.dd-theater-collapsible-inner` wrapper pair that receives `.dd-theater-collapsed` when `IsContentHidden` is true — animates `grid-template-rows: 1fr → 0fr`, `opacity`, and `visibility` (deferred via `transition-behavior: allow-discrete`) so Theater ON/OFF eases rather than pops; `prefers-reduced-motion` collapses instantly. The same wrapper pattern drives the player-bar `NowShowingPanel`, which is now kept mounted whenever a release is playing and collapsed (not `@if`-removed) when Theater is OFF — enabling the ease-in when Theater turns ON (resolves OQ2 design intent for a mounted-but-dormant panel). (3) **Playing-release scoping:** Theater Mode now only applies to the currently-playing release. `ReleaseDetailBase` and `CutDetailBase` each gained a cascaded `IStreamingPlayerService PlayerService`, a reference-guarded `StateChanged` subscription (disposed in `Dispose`), and three predicates: `IsThisReleasePlaying` (`CurrentTrack?.Release?.EntryKey == EntryKey`), `IsContentHidden` (`TheaterMode && IsThisReleasePlaying`), `ShowTheaterToggle` (`(LavaEnabled || WaveformEnabled) && IsThisReleasePlaying`). `TheaterModeToggle.razor` gained an `Available` parameter (default `true`) folded into its render gate; all three pages pass `Available="ShowTheaterToggle"`. A detail page whose release is not playing shows no toggle and ignores the global `TheaterMode` flag.

- `AppNavLink.razor`: Nav link with active-page highlight.
|
||||
- `AudioPlayerProvider.razor`: Cascading host for `IStreamingPlayerService`. Everything inside it gets the player via `[CascadingParameter]`.
|
||||
- `StreamNowButton.razor`: Reusable streaming-trigger button. Fetches a random track, warms the AudioContext (Safari gesture requirement), and starts streaming — routes through `IQueueService.PlayTrack` (deque PLAY semantics) when the queue cascade is present, falls back to `IStreamingPlayerService.SelectTrackStreaming` when absent. Accepts `ButtonClass` and `ButtonLabel` for distinct visual presentations; `OnStreamStarted` EventCallback for post-stream side effects (e.g., mobile menu close).

- `AudioPlayerBar.razor`: Dock UI at the bottom (play/pause/seek/volume). In Fixed (embed) mode, renders an always-shown read-only queue panel below the controls when `ShowFixedPanel && _fixedPanelOpen` (release embeds only; single-track embeds stay panel-free). The Queue button in Fixed mode toggles `_fixedPanelOpen` and triggers a `postHeight` call via `embed-frame.ts` so the host page can resize the outer iframe. TypeScript counterpart for the resize handshake: `DeepDrftPublic/Interop/embed/embed-frame.ts` — reads `EmbedId` from `window.location.search`, exports `postHeight(element)` which measures the player element and posts `{type:"deepdrft-embed-resize", height, embedId?}` to `window.parent`; no-ops when not framed (compiled output gitignored). **Phase 20:** injects `WaveformVisualizerControlState` and subscribes to `Changed` (added alongside the existing `IPlayerService.StateChanged` subscription — same reference-guard + dispose pattern); mounts `<NowShowingPanel Release="CurrentTrack.Release" />` above the transport controls when `VisualizerControlState.TheaterMode && CurrentTrack?.Release is not null`.

|
||||
- `AudioPlayerBar/PlayerControls.razor`: Play/pause/stop buttons in the transport zone. Renders via `<PlayStateIcon>`. In embedded (`Fixed`) mode, skip-previous and skip-next render when `!Fixed || HasPrevious || HasNext` — so a release embed (which has a queue) shows forward/back navigation while a single-track embed (no queue) hides them; the Stop button is hidden in all embed contexts (`!Fixed` only).
|
||||
- `AudioPlayerBar/TrackMetaLabel.razor`: Now-playing track-title + artist row. Takes `[Parameter] bool Fixed` (passed from `AudioPlayerBar.razor`). When `Fixed` (embedded iframe), the track-title anchor renders with `target="_blank" rel="noopener noreferrer"` so clicking it opens the release detail page in a new tab; the docked (non-embedded) player keeps same-tab nav. When no release is attached the title renders unlinked in both modes.
|
||||
- `AudioPlayerBar/NowShowingPanel.razor`: Phase 20 "now showing" presentational band rendered by `AudioPlayerBar` **only when** `VisualizerControlState.TheaterMode && CurrentTrack?.Release is not null`. Carries the release identity the hidden detail page would otherwise show: cover art thumbnail (`deepdrft-track-detail-cover-art` / `deepdrft-gradient-soft-secondary` placeholder), release title linked via `ReleaseRoutes.DetailHref(Release)`, and a release-mode `SharePopover` (`ReleaseEntryKey` + `ReleaseMedium`) wrapped in `.dd-accent-icon`. `[Parameter, EditorRequired] ReleaseDto Release` — non-null by the bar's mount gate. Purely presentational: owns no player logic, no Theater state, and no data fetch. Layout CSS lives in `AudioPlayerBar.razor.css` (`.now-showing` / `.now-showing-cover` / `.now-showing-cover-art` / `.now-showing-cover-placeholder` / `.now-showing-title-link` / `.now-showing-title` / `.now-showing-share`); all surface/text binds `--deepdrft-page-*` theme-aware aliases — no new dark overrides.

- `WaveformVisualizer.razor`: The single WebGL2 lava-lamp visualizer engine. Hosts the waveform of whatever track is currently playing/selected. Three hosting modes: mode A (Mix detail — full-bleed centerpiece), mode B (Cut/Session detail — ambient layer behind hero+content via `ReleaseDetailScaffold`'s `Ambient` slot), mode C (NowPlaying hero panel — full-bleed background for the home hero's right side, mounted by `NowPlaying.razor` inside `.np-visualizer-bg`). `[Parameter] bool Fill` switches from fixed-viewport positioning to container-relative sizing (CSS-only; the renderer is identical in both modes). The bridge resolves the current track's `EntryKey` and re-fetches the high-res datum on track change. Subscribes to `WaveformVisualizerControlState.Changed` and pushes each updated dial to the WebGL module via JS interop. Follows the live playing track (keys on host `TrackId` match OR shared host `ReleaseEntryKey`).
|
||||
- `WaveformVisualizerControls.razor`: The waveform visualizer control panel (content hosted by `WaveformVisualizerControlPopover`). Phase 15 re-layout: a deterministic **three-row sectioned layout** encoding the visualizer's two subsystems. Row 1 (MODE, always visible): two iconographic lamp toggles (lava on/off, waveform on/off) left-aligned + collisions knob (conditional — only when both subsystems on) + color knob pinned far-right. Row 2 (LAVA, visible only when `LavaEnabled`): "LAVA:" section label + Gravity / Heat / FluidAmount / FluidViscosity knobs. Row 3 (WAVE, visible only when `WaveformEnabled`): "WAVE:" section label + scroll-speed `MudSlider` (not a knob) + width knob pinned far-right. Total: two lamp toggles, seven `RadialKnob`s, one `MudSlider`. Colour principle: lamp toggles / knob arcs / slider are green (`Color.Primary` — interactive); section labels / knob caption icons are light (static). Each control has a playful `MudTooltip`. `[Parameter] bool PanelChrome` scopes panel chrome (NowPlayingCard look — square corners, lighter-navy, thin border) to the popover mount; chrome classes live in the global `deepdrft-styles.css` (CSS isolation cannot reach portaled overlay content). `[Parameter] bool Visible` gates the rows via `@if` while the container holds reserved min-height. Owns no JS interop: mutates the injected `WaveformVisualizerControlState` and raises `Changed`. No control is a seek surface (read-only contract).
|
||||
- `WaveformVisualizerControlPopover.razor`: Pairs the lava-lamp icon button with `WaveformVisualizerControls` as a **screen-centered tinted modal** (Phase 15). The primitive is `MudOverlay` (`DarkBackground="true"`, `Modal="true"`) — **not** `MudPopover`; `AnchorOrigin`/`TransformOrigin` parameters do not exist (a centered modal has no anchor). Clicking the lava-lamp icon opens the overlay; clicking the scrim closes it (knob-drag-safe: `RadialKnob`'s `position:fixed` capture div sits above the scrim during a drag, so releasing outside the panel never fires the close handler). The panel stops click propagation so an inside click is not a dismissal. `[Parameter] Size IconSize` controls the trigger-icon size (default `Large`). This is the unit every host places — one icon anywhere gives the full control panel centered on screen, regardless of where the icon sits. 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`).
|
||||
- `TheaterModeToggle.razor`: Phase 20 Theater-Mode toggle button. Visible only when `State.LavaEnabled || State.WaveformEnabled` (no visualizer subsystem active → no theater to enter). Disabled until interactive (`!RendererInfo.IsInteractive`), same guard as Play and the lava-lamp trigger. On click: flips `WaveformVisualizerControlState.TheaterMode` and calls `NotifyChanged()`. Shows an on/off `aria-pressed` active state. Glyph: Material `Theaters`. `.dd-accent-icon` container gives the green-accent glyph in both themes with zero new CSS — same treatment as `WaveformVisualizerControlPopover`. Subscribes to `State.Changed` in `OnInitialized` and unsubscribes on `Dispose` to re-render when another observer (e.g. `CoerceTheaterMode()`) flips the state. `[Parameter] Size IconSize` (default `Large`) matches the adjacent lava-lamp trigger. Placed **immediately left** of the lava-lamp popover on all three detail pages inside a `.dd-detail-top-actions` cluster.
|
||||
- `TheaterModeToggle.razor`: Phase 20 Theater-Mode toggle button. Visible only when `Available && (State.LavaEnabled || State.WaveformEnabled)` — no visualizer subsystem active → no theater to enter; `Available` is false when this page's release is not the one currently playing (Phase 20 Wave 2). Disabled until interactive (`!RendererInfo.IsInteractive`), same guard as Play and the lava-lamp trigger. On click: flips `WaveformVisualizerControlState.TheaterMode` and calls `NotifyChanged()`. Shows an on/off `aria-pressed` active state. Glyph: Material `Theaters`. `.dd-accent-icon` container gives the green-accent glyph in both themes with zero new CSS — same treatment as `WaveformVisualizerControlPopover`. Subscribes to `State.Changed` in `OnInitialized` and unsubscribes on `Dispose` to re-render when another observer (e.g. `CoerceTheaterMode()`) flips the state. `[Parameter] Size IconSize` (default `Large`) matches the adjacent lava-lamp trigger. `[Parameter] bool Available` (default `true`) — the page passes its `ShowTheaterToggle` predicate here so the toggle is scoped to the playing release; surfaces with no release-scoping pass the default `true`. Placed **immediately left** of the lava-lamp popover on all three detail pages inside a `.dd-detail-top-actions` cluster.
|
||||
- `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`.
|
||||
- `NowPlayingStats.razor`: Home hero stat row. Three cards: Studio Cuts (total Cut-medium track count + zero-suppressed per-`ReleaseType` Cut release breakdown), Mixes (`MixReleaseCount` labelled "Sets" + `hh:mm` total mix runtime via `RuntimeFormat`), and Plays (live `TotalPlays` odometer in `.hero-stat-odometer` + `UniqueListeners` "N listeners" secondary line via `.hero-stat-sub` — Phase 16 wave 16.5). All three cards read from the same `HomeStatsDto` round-trip; no extra fetch path. Fetches via `IStatsDataService` on init; bridges the prerender fetch across the WASM seam with `PersistentComponentState` (persists only on a successful load, matching the medium-browse bridge pattern). Implements `IDisposable` to release the `PersistingComponentStateSubscription`.

Each has a matching `Default*` const. `Changed` event is the decoupling seam — controls mutate state + raise `Changed`; the bridge (`WaveformVisualizer`) subscribes and pushes the affected uniform or subsystem-enable; the Theater observers (the three detail pages and `AudioPlayerBar`) subscribe to react to `TheaterMode`. **`CoerceTheaterMode()`**: enforces the invariant that Theater Mode cannot remain on when both subsystems are off — called from `WaveformVisualizerControls.ToggleLava`/`ToggleWaveform` **before** `NotifyChanged()` so all observers see a consistent, coerced state in the same `Changed` cycle. `TheaterMode` is a page-chrome presentation flag; the visualizer bridge ignores it. Scoped DI so state survives SPA nav within a session and resets on fresh page load.

Both base classes also subscribe to `IStreamingPlayerService.StateChanged` (idempotent, reference-guarded, disposed) so the predicates re-evaluate live when playback moves between releases.
|
||||
- `PlayTracker`: Per-session play-session tracker (Phase 16 wave 16.1). Opens on playback start, advances a high-water position on each progress tick (from `StreamingAudioPlayerService` — not the HTTP layer, so seek-beyond-buffer re-fetches are the same play), closes on track-switch / stop / organic-end / page-unload. Engagement floor: ≥3 s OR ≥5% of duration. Three-bucket classification (`partial`/`sampled`/`complete`). Emits at most one event per session via `IPlayEventSink`. No player or JS dependency — testable against a fake sink.
|
||||
- `ShareTracker`: Per-session share tracker (Phase 16 wave 16.1). Called by `SharePopover` after a successful clipboard write; applies a 60-second per-(target, channel) debounce. Sends via `BeaconInterop`. Scoped so debounce memory resets on fresh page load. **Wave 16.3:** injects `IAnonIdProvider`; attaches `_anonId.Current` to `ShareEventDto.AnonId` (omitted when null).
|
||||
- `BeaconInterop`: `navigator.sendBeacon` JS interop wrapper (Phase 16 wave 16.1). Fires JSON payloads to `api/event/{play,share}` fire-and-forget. Also wires a page-unload handler that flushes any pending play event when the page is torn down.

**Layout-only cluster class: `.dd-detail-top-actions`.** When two or more icon affordances sit together in a top-action row (e.g. the Theater toggle + lava-lamp popover on the three detail pages), wrap them in `.dd-detail-top-actions` — a layout-only `display:flex; align-items:center; gap:0.25rem` class in `deepdrft-styles.css`. No colour; prevents the `SpaceBetween` row from spreading the icons apart. Each affordance inside still carries its own `.dd-accent-icon` wrapper independently.
|
||||
|
||||
**Full-screen detail body: `.dd-detail-fill`.** Phase 20 Wave 2. Applied to each detail page's foreground content container (the `<div>` or `<MudContainer>` that wraps the scaffold/hero); sets `min-height: calc(100vh - var(--deepdrft-nav-height, 88px))` so the ambient/full-bleed visualizer reads as genuinely full-screen and the site footer is pushed below the fold, independent of Theater Mode. Reuses `--deepdrft-nav-height` (88px desktop / 72px mobile) so the clearance tracks the nav bar height across breakpoints; no new layout token. Defined in `deepdrft-styles.css`.
|
||||
|
||||
**Eased Theater Mode collapse: `.dd-theater-collapsible` / `.dd-theater-collapsed`.** Phase 20 Wave 2. Used wherever Theater Mode should ease content in/out rather than pop via `@if`. The outer wrapper carries `.dd-theater-collapsible` (always present); its single direct child carries `.dd-theater-collapsible-inner`; adding `.dd-theater-collapsed` to the outer collapses the region. Technique: `grid-template-rows: 1fr → 0fr` (real-height interpolation), `opacity`, and `visibility: hidden` + `transition-behavior: allow-discrete` (visibility flip deferred to end of ease-out so collapsed content is removed from the tab order once the animation completes; immediately re-shown on expand). A `prefers-reduced-motion` block collapses instantly. Used on the release content regions in all three detail pages (`IsContentHidden` predicate) and on the player-bar `NowShowingPanel` band (collapsed when `!TheaterMode`). Defined in `deepdrft-styles.css`.

The former dark nav rule (`.deepdrft-theme-dark .dd-nav-actions .mud-icon-button`) has been removed as dead. `DDIcons.GasLamp` (light-mode icon) continues to use `currentColor` and inherits nav text colour in light (the unlit toggle is theme-divergent by design).

|
||||
|
||||
Product spec. Status: **landed and merged to dev — 2026-06-20** (pending final manual browser/GPU smoke-test on dev). All §9 open questions resolved at sign-off 2026-06-20.

Product spec. Status: **landed and merged to dev — 2026-06-20; Wave 2 refinements landed 2026-06-21.** All §9 open questions resolved at sign-off 2026-06-20.
|
||||
Surface: **public listener site only** (`DeepDrftPublic` / `DeepDrftPublic.Client`). No CMS
|
||||
(`DeepDrftManager`) change. No API, data, or schema change — Theater Mode is a pure
|
||||
presentation-layer feature riding data the player already carries.
|
||||
|
||||
**Wave 2 refinements (landed 2026-06-21):** Three post-ship improvements. (1) *Full-screen detail body* — each detail page's foreground container gained `.dd-detail-fill` so the visualizer reads full-screen and the footer is pushed below the fold regardless of Theater Mode. (2) *Eased collapse* — the hard `@if` content-hide on all three detail pages and the player-bar `NowShowingPanel` was replaced by a `.dd-theater-collapsible` / `.dd-theater-collapsed` CSS pair (`grid-template-rows: 1fr → 0fr` + `opacity` + deferred `visibility`); the panel now stays mounted and collapsed rather than unmounting via `@if` (enables the ease-in; resolves OQ2 design intent). (3) *Playing-release scoping* — Theater Mode now only applies to the currently-playing release: `ReleaseDetailBase` / `CutDetailBase` each gained a cascaded `IStreamingPlayerService` subscription and predicates (`IsThisReleasePlaying`, `IsContentHidden`, `ShowTheaterToggle`); `TheaterModeToggle` gained an `Available` parameter; all three pages pass `Available="ShowTheaterToggle"`, so a detail page whose release is not playing shows no toggle and ignores the global flag.
