jakeandClaude Opus 4.6 2ee20a6aff Tint title page accent colors to poster's vibrant color
Override CSS custom properties (--primary, --ring, --primary-foreground,
--status-watching) on the title detail page wrapper using the vibrant
color from the poster's node-vibrant palette. All Tailwind classes
referencing these variables automatically pick up the new color.

Also await lazy color extraction in getTitleWithChildren() so palettes
are available on first visit to never-before-opened titles.
