Toggle left of the lava popover hides release content so the visualizer fills the surface; player bar grows to carry the playing release's cover, title, and share. State on WaveformVisualizerControlState; pages and bar observe it.

@* Theater-Mode toggle (Phase 20 §3). The single affordance placed identically on all three release
|
|
detail pages — immediately to the LEFT of the lava-lamp WaveformVisualizerControlPopover trigger.
|
|
It is purely a mutation surface: tapping it flips State.TheaterMode and raises Changed; the detail
|
|
pages observe that to gate their content @if, and the player bar observes it to grow. This component
|
|
reaches into no page and no bar — single source, multiple observers (§6).
|
|
|
|
Visible only when the lava OR waveform subsystem is on — there is nothing to go to theater FOR if both
|
|
are off (§3.2). Disabled until interactive (§3.4), the same prerender guard the lava/Play buttons use.
|
|
Active visual state when Theater is ON. .dd-accent-icon gives the green-accent glyph in both themes
|
|
with zero new CSS (§8) — same treatment as the lava-lamp trigger it sits beside. *@
