- Dark surface vars changed from purple-navy (8 8 22) to neutral near-black (10 10 12)
so sky/emerald/amber accent themes no longer have a purple cast
- Light surface vars made nearly neutral (252 252 253) — lavender tint removed
- All rgba(100, 80, 160, ...) replaced with rgb(var(--accent-400) / ...) in
.app-surface, .app-surface-strong, and .app-toolbar shadows/borders
- .app-page-title dark gradient midpoint changed from hardcoded #e8e4ff to
rgb(var(--accent-100)) so it adapts to the chosen accent color
- Body light-mode background gradient opacity reduced to avoid over-tinting
