* feat(appearance): add theme, accent, contrast, and typography personalization
Expand Settings to Appearance into a full personalization surface and add a
quick switcher to the top bar (the palette button between search and
notifications). Choices are saved to the browser, sync across tabs, and apply
before first paint so there is no flash on reload.
- Themes: Dim (the default raised charcoal), OLED true black, Light, and Auto
(follows the OS and re-resolves live when it flips).
- Accent: an eight-hue wheel (cyan default) that drives the one data color
across charts, rails, focus rings, active states, and the ambient glow.
- Fine-tune sliders: a master Contrast that spreads page, ink, and borders
together, plus Border brightness and Ambient glow.
- Typography: swappable interface (Geist / IBM Plex Sans / Hanken Grotesk) and
data (Geist Mono / IBM Plex Mono / Fira Code) faces, and a text-size control
(continuous slider in Settings, S/M/L/XL presets in the popover, kept in
sync). The display serif stays locked as the signature face.
Surfaces, borders, and ink derive from per-theme lightness values so the live
knobs scale the whole UI through CSS, and the opaque directional borders read on
every panel including true black. A live preview reflects changes in real time.
Adds a documentation page under Features.
* fix(appearance): keep contrast-driven tokens in gamut and add picker keyboard nav
Clamp the contrast and knob driven surface, border, and ink lightness so the
full slider range stays a valid color. The page now always sits below the card
tone, so page/card separation no longer collapses at high contrast in Light; the
lit border edge never reaches white in Light at the low end of the knobs; and the
OLED and Dim extremes resolve to valid black/white instead of out-of-range values.
Add the radiogroup keyboard model (roving tabindex plus Arrow / Home / End) to the
accent and type pickers through a shared hook, matching the segmented control. One
item is tabbable and arrow keys move focus and selection together.
* feat(search): add global command palette with cross-node stacks
Press Ctrl+K from anywhere to open a search palette that jumps to
pages, switches nodes, or opens stacks on any online node in the
fleet. Trigger lives as an icon in the top bar. Replaces the former
sidebar-scoped Ctrl+K handler.
The cross-node stack search fan-out is extracted into a shared hook
so the sidebar and palette stay in sync on the same debounce +
abort shape.
* fix(search): drop render-time ref write and effect-based query reset
Replace `nodesRef.current = nodes` during render with direct use of
`nodes` in the stack select callback, and fold the query-reset logic
into a single `onOpenChange` handler so it no longer runs via an
effect. Both changes resolve react-hooks rule violations that broke
frontend lint in CI.
Replace the sliding accent pill and blurred underline with material-at-
rest tabs that speak the cyan identity language used elsewhere in the
chrome. Each tab is a full-height button with a tracked-mono uppercase
label, and the active tab carries a crisp 2px cyan rail flush with the
bar's bottom edge.
Drops the <Highlight> primitive, the springs import, and the unused
navTabValue memo/prop from EditorLayout.
Extract the app header into a dedicated TopBar component and apply the
same translucent chrome language used by the sidebar: bg-sidebar +
backdrop-blur-md + inset top highlight. A new --chrome-top-highlight
token drives the highlight in both themes via the shadow-chrome-top
utility alias.
Restore the pulsing-dot unread indicator on the notification bell
(replaces the temporary count pill) and keep its aria-label dynamic so
screen readers still hear the unread count. Tighten nav a11y with
aria-current on the active item, aria-label on icon-only buttons, and a
proper <nav> landmark around the desktop Highlight group.
