Root cause both buttons looked black: --ve-accent was space-separated
(1 180 228) but used in rgba(var(--ve-accent), a) -> invalid 'rgba(1 180 228, a)'
so the color silently failed. Switched --ve-accent to comma-separated (matching
music's --accent-rgb) and fixed all fallbacks -> the accent + glow now render.
- TMDB: vibey light blue (56,189,248); TVDB: purple (168,85,247).
- TVDB brand mark inverted everywhere (dashboard button, modal rail, settings
frame) so the dark logo reads on the dark UI.
