Add Theme::var(name, ctx) (CSS custom-property getter) and Theme::apply_to_egui(ctx)
which maps the palette onto egui's global Visuals so standard widgets share the
theme colors. Add a mobile::palette::Palette built from the theme each frame and
replace the duplicated per-file C_* color constants across all mobile modules
(omni, topbar, stack, inspector, transport, intent, shell) with it. Add --scrim
and --accent-* category vars to styles.css. Apply the theme visuals every frame in
update(). Mobile and the main UI now share one CSS-variable-driven palette that
responds to light/dark/user themes.
Omnibutton (mobile/omni.rs): a context FAB whose radial holds the active layer's
drawing tools laid out in a staggered inner/outer arc, plus a "+New" petal
(create Vector/Audio/MIDI/Raster/Video layer, Group, Import, and Split/Duplicate
when a clip is selected — dispatched as MenuActions) and a "more" petal that
opens a full-tools grid when the layer has extra tools. Contextual: the tool ring
only appears when the Stage is in the visible window; off-Stage the FAB is a
"+New" create button. Tools/creates use Lucide icons. Pane-internal adds
(nodes/notes/instruments) deferred to P6.
Playback fix: document.current_time (read by the renderer for animation eval and
video-frame decode) was only synced from the audio playback position inside
TimelinePane::render_content. In the mobile shell, panes render on demand, so with
the timeline off-screen current_time went stale and the Stage froze during
playback. Move the sync into the per-frame block in update() so it runs regardless
of which panes are visible.
