Only stamps body class on firstRender or _isDarkMode change; adds base call.
Hoists duplicate dark popover mix value to --deepdrft-popover-surface-dark in :root;
both .deepdrft-theme-dark and body.deepdrft-theme-dark reference it via var().
MudBlazor popovers portal to <body>, outside the theme wrapper, so the dark token
was unreachable. MainLayout now stamps deepdrft-theme-dark on <body>. Light: 8%->4%
navy (near page background); dark: navy-mid + 20% green-accent (bluer).
Re-point neutral page surfaces, play-chip, and default popover from constant brand tokens to theme-aware aliases defined twice in deepdrft-tokens.css. Decorative navy/green sections and bespoke dark-glass panels untouched. Appbar-navy symptom deferred (palette C#, out of CSS scope).
Mute --deepdrft-panel-ground; WAVE scroll MudSlider back to RadialKnob; new DDIcons Waveform/WaveformFilled glyph for the waveform toggle; strong green ON-state chip vs dim OFF; refresh popover pointer-capture comment.
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.
TrackCard, TracksGallery, DDIcons, DeepDrftPalettes (Default+Cms), DeepDrftFontLinks,
and palette CSS tokens extracted. Both hosts and DeepDrftCms reference the shared RCL.
