Shadow-DOM components carried fallback colors that never matched the
actual tokens: panel-tab-strip fell back to teal #4ec9a8 for the coral
--accent, resizable-divider to Bootstrap blue #007bff, and --border to a
generic #333. Align all fallbacks with the claw-family values in
styles/base.css so token-less rendering matches the product palette.
Also document the intentionally dark image-lightbox chrome and the
terminal theme's hand-mirrored token values, and regenerate the drifted
values in ui/docs/design-system/color-tokens.md (--muted, --muted-strong,
--primary, --danger, --info, light status colors) from base.css truth.
* feat(ui): add settings design-language foundation (tokens, settings.css, helpers)
* refactor(ui): move settings workspace shell styles into settings.css
* refactor(ui): migrate all settings surfaces to the unified settings design language
Every settings surface (General quick+advanced schema form, Appearance,
Communications, Automation, MCP, Infrastructure, AI Agents, Channels,
Connection, About, Profile, Model Providers, Plugins, Skills, Skill
Workshop chrome, Devices, Worktrees, Debug, Logs, Activity, Automations,
Sessions, Usage chrome) now renders through the settings-ui helpers and
settings.css: sections as plain uppercase headings outside one flat
group surface, hairline-divided rows, a single toggle/segmented/status
vocabulary, status dots instead of pills, and no cards-in-cards or enter
animations. Deletes the qs-*/cfg-*/config-section-card/account-card/
plugins-row/cron-editor-card/session-badge/agent-pill families and
orphaned shared rules.
* style(ui-docs): format design-system docs
* fix(ui): make activity statusKind lookup exhaustive for consistent-return lint
* fix(ui): address settings design-language review findings
Label-wrapped toggle rows with required accessible names, named selects
and cron form controls, busy-disabled segmented controls with restored
theme-transition anchors, collapsible skill groups, semantic plugin
headings, gateway connected status, paired-devices empty state, logs
subtitle, cron prompt help, and keyboard-accessible session goal
objectives.
* fix(ui): harden settings primitives per review round two
Wrap row action clusters, fully-inset nav focus ring, restore number
steppers in the schema form, cap node capability lines, keep the named
Activity region landmark, and associate cron help text via the row
label.
* fix(ui): skip empty section headings and fix the toggle doc example
* docs(ui): import renderSettingsToggleRow in the settings example
* fix(ui): rename number stepper delta to avoid shadowing
* feat(ui): session-first sidebar, context ring, and warm light theme for Control UI
* test(ui): drop unnecessary non-null assertion in sidebar recents test
