Design tokens
- Fix WCAG AA text failures: darken light muted text and lighten dark
tertiary text so 13-14px copy clears 4.5:1 on every surface.
- Rebuild the dark surface ladder in correct values (oklch compresses to
near-black below ~15%), giving visible steps: content, chrome, cards.
- Establish a 3-layer shell (deep content, lighter sidebar/topbar chrome,
lifted cards) with crisp hairline rings and a restrained card shadow.
- Unify every surface to one neutral temperature (pure gray); neutralize
the cool-tinted sidebar text and legacy surface tokens.
- Convert all color tokens to oklch (neutrals + brand).
- Unify inputs to the recessed token; fix invisible dark placeholders.
- One shared --shadow-dropdown for all menus/listboxes/command palette.
Settings sidebar
- Sticky contained-card rail with subtle scrollbar; collapsible sub-section
groups (active open by default), cross-page section links.
- Mobile: collapsible disclosure with animated open, outside/Escape dismiss,
press feedback, and reduced-motion support.
Mobile
- Consolidate the resource header (title + status + links on one row).
- Tighten settings-page vertical rhythm.
- Rebuild the main sidebar as an animated shadcn-style sheet (slide/fade,
Escape, scroll lock, in-panel close, close-on-navigate).
Fixes
- #11532: selected server invisible in the light-mode terminal toolbar.
