/* Eased content collapse for Theater Mode (Phase 20 Wave 2 §2). The detail content stays mounted and
   collapses smoothly when .dd-theater-collapsed is applied, so toggling Theater eases both directions
   instead of popping — when collapsed the content is fully out of the way and the visualizer is
   unobstructed. The same pattern drives the player-bar "now showing" band so the bar grows/shrinks
   smoothly too.

   Technique: grid-template-rows 1fr → 0fr interpolates the REAL content height (no 400vh ceiling
   artifact / delayed-start that the old max-height approach had). The direct child receives
   overflow:hidden + min-height:0 so it actually clips during the transition (the grid child is the
   collapsing unit). visibility:hidden removes all descendants from the tab order and from pointer/
   keyboard interaction once collapsed — this fixes the Major accessibility defect where Tab could
   reach hidden controls. transition-behavior:allow-discrete makes visibility flip discretely: it
   flips to hidden AFTER the ease-out finishes (so the animation plays fully), and flips back to
   visible BEFORE the ease-in starts (so content is immediately interactive on the way back in).
   The visibility transition duration matches the height ease (0.45s) so allow-discrete has a real
   interval to defer against: on collapse the flip to hidden is held until t=0.45s; on reopen it
   fires at t=0 (immediately interactive). A 0s duration would fire the flip at t≈0 on collapse,
   defeating the deferral and hiding content before the ease-out finishes. */

   WAVEFORM VISUALIZER CONTROL PANEL  (Phase 12 §3d-revised / §3g → Phase 15 re-layout)
   The control deck hosted inside WaveformVisualizerControlPopover, now a screen-centered
   tinted MudOverlay (Phase 15 §4). MudOverlay — like the former MudPopover — PORTALS its
   content out of the component's DOM subtree, so Blazor CSS isolation never reaches the
   rendered panel: its chrome, the three-row/section LAYOUT, the section labels, the slider,
   and the toggles all live here in the global sheet, not in the scoped
   WaveformVisualizerControls.razor.css. (The scoped file keeps only the legacy inline-bar
   fallback Mix's old TopRowCenter mount used, which is not portaled.)

   The waveform-visualizer-control-panel class is applied ONLY when the component's
   PanelChrome="true" parameter is set — which the popover host does and Mix's inline mount
   does NOT — so the chrome never leaks onto an inline bar.

   CHROME (Phase 15 §5 — NowPlayingCard treatment): SQUARE corners, lighter-navy ground
   (navy-mid), a thin LIGHT border (--deepdrft-border-light, the NowPlayingCard 0.12-alpha
   light-on-dark idiom as a token). All token-sourced; no hardcoded hex.

   COLOUR PRINCIPLE (§5 — green = interactive, light = non-interactive): the RadialKnob reads
   --mud-palette-* for its arc/pointer/center/label; we pin --mud-palette-primary to the green
   accent (interactive arcs/pointers) and --mud-palette-text-primary to light. Caption icons and
   section labels are LIGHT (static). The slider track/thumb and the lamp toggles are green.

/* ── The modal overlay (Phase 15 §4). MudOverlay is already a full-viewport flex scrim that centers its
   content (.mud-overlay { display:flex; align-items:center; justify-content:center }), which gives the
   screen-centered panel on every host for free — we do NOT fight that positioning. We:
   (a) Raise the overlay z-index above the header (100) and the player-dock footer (1200/1300) so the
       scrim tints the ENTIRE viewport uniformly — header and footer included (defect #7). The panel
       content needs z-index: auto (inherits from stacking context) so it sits above the scrim naturally;
       the RadialKnob capture div at 9999 remains above everything.
   (b) Set the mild tint from the SINGLE --deepdrft-modal-scrim-alpha token (§10.5, defect #6).
   (c) Remove overflow-y:auto on the content wrapper — it was the source of the drag scrollbar (defect #2).
       The panel's max-width/flex-column already contain its size; the outer overlay clips at 100vh.
   (d) Suppress body scroll while the overlay is present so no page-scroll occurs during a drag (defect #2).
   The overlay portals to the body, so these are plain global rules (no scope attribute). The doubled
   .mud-overlay-scrim.mud-overlay-dark selector (0,2,0) outranks MudBlazor's own .mud-overlay-dark (0,1,0),
   so the tint wins regardless of stylesheet load order. ── */

   INTERACTIVE-ACCENT ICON TREATMENT  (.dd-accent-icon / .dd-accent-fill)
   ----------------------------------------------------------------------------
   The single, reusable green-accent treatment for interactive icon affordances —
   replaces the per-site dark-mode overrides that previously had to fight the palette.

   WHY a class and not a palette colour: no MudBlazor Color enum is green in BOTH
   themes (Dark.Secondary is off-white, Dark.Primary is green; Light.Secondary is
   green, Light.Primary is navy), so every "green in both" affordance had to be
   patched per-site. --deepdrft-green-accent (#3D7A68) is the brand constant — the
   SAME value in both palettes — so a non-theme-scoped rule is correct: light already
   renders these glyphs green-accent (via Color.Secondary → Light.Secondary), so this
   keeps light pixel-identical while fixing dark.

   WHY it reaches the glyph: MudBlazor colours a Color.Secondary icon by stamping
   .mud-secondary-text on the inner .mud-icon-root <svg>, and that rule is `!important`
   (color: var(--mud-palette-secondary) !important). Targeting only the .mud-icon-button
   wrapper therefore never wins — the svg keeps its own !important colour. The documented
   override bug. The glyph clause .dd-accent-icon .mud-icon-button .mud-icon-root is
   specificity (0,3,0) + !important, which beats MudBlazor's standalone .mud-secondary-text
   (0,1,0) + !important on specificity alone — source order is not load-bearing for the
   glyph clause. The .mud-icon-button selector carries the
   Color.Inherit affordances (lava-lamp glyph inherits the wrapper colour, no
   .mud-secondary-text to fight); the spinner covers the PlayStateIcon loading state.

   Apply .dd-accent-icon to a CONTAINER of the affordance(s); add .dd-accent-fill
   alongside it when the container ALSO holds a filled MudButton whose Color.Secondary
   fill must go green-accent in dark (a filled button is a background fill, not a glyph —
   light already renders green-accent fill + white text, so .dd-accent-fill is DARK-ONLY
   to keep light pixel-identical). The Session/Mix hero Share/Play glyphs use this class
   too (they were already green-accent in light via Color.Secondary, so folding them in
   keeps light pixel-identical and fixes dark — the over-image glyphs are not actually
   theme-divergent). The one genuinely theme-divergent affordance (gas-lamp = inherited
   nav text in light) does NOT use this class — it keeps a dark-only rule below.

   The glyph rule targets glyphs inside an ICON button (.mud-icon-button .mud-icon-root)
   only — the filled Play button is a .mud-button-filled (not .mud-icon-button), so its
   StartIcon is naturally excluded and keeps its own contrast colour (white in light,
   navy in dark). The bare .mud-icon-button selector carries the Color.Inherit case
   (lava-lamp glyph inherits the wrapper colour); the spinner covers the loading state. */
