* feat(appearance): add Calm/Signature visual style, readability mode, and chart palette
Turn the "too intense / italic headers hurt / the security graph fights my
eyes" feedback into a token-driven Visual style with Calm as the new default
and Signature one click back to the prior look.
- Heading family routes through a `.font-heading` utility driven by
`--font-heading`/`--heading-style`: operational headings render upright in the
interface face under Calm and italic Instrument Serif under Signature. Base
rule sets family + style only, so each call site keeps its own weight/tracking
and Signature stays a true no-op; the Calm lift is a `[data-headings="clean"]`
descendant rule. Brand lockup, empty-state heroes, and onboarding stay serif.
- Severity charts resolve through `--sev-*` tokens with Muted, Heat, and
Signature palettes; FindingsByType routes its series through the severity ramp
plus a neutral so no brand-cyan sits next to rose. The risk trend flattens its
gradient under Muted/Heat/reduced and keeps the gradient under Signature.
- Appearance settings gain Visual style cards, a Security visualization palette,
a Readability master toggle, a Motion & effects group, and a "Reset to default"
button (restores the Calm axes, disabled while readability is on). Contrast
moves under Readability and Ambient glow under Motion & effects. A card is
selected only while the stored sub-axes match its preset, so a custom
combination de-selects both.
- The topbar Theme quick-switch swaps the interface/data font pickers for a
Visual style switch and a Readability toggle (text size kept); its footer
Settings link jumps straight to Appearance.
- Readability is a sticky master that forces the calm resolution and a contrast
lift at apply time without mutating the stored sub-axes.
- New users default to Calm; any pre-existing persisted appearance state keeps
the Signature look. The pre-paint script mirrors the store.
- SegmentedControl gains a `disabled` prop and a nullable value (no active
segment for a custom combination, with a roving-tabindex keyboard anchor).
Adds unit/component coverage for the store, migration, chart shape logic, the
disabled control, the reset/de-selection, and the quick-switch.
* fix(appearance): migrate Blueprint serif headings and surface readability locks
- Migrate the two operational Blueprint headings (catalog tile name, drift-policy
option title) from font-serif italic to the .font-heading utility; the first
pass only covered font-display, so Calm still left these italic. font-serif and
font-display both resolve to the same display face, so this is the same fix.
- Lock the Visual style cards under Readability (parity with the topbar switch and
the on-screen guidance to turn Readability off to choose a style by hand).
- Lock the Border brightness slider under Readability and show its forced +0.03
readout, since Readability overrides the stored value; dragging it previously
appeared to do nothing.
- Correct the Appearance docs sentence for the topbar quick switch (it listed
fonts; the quick switch now carries visual style, readability, and text size).
Drop the cursor-following hover tooltips from the masthead stat tiles: the RUNNING
tile on the Home dashboard (the managed / external / exited breakdown) and the
CONTAINERS tile on the Fleet view (the running / total split). Both revert to plain
stat tiles, matching the CPU and MEM tiles beside them. The dashboard and fleet docs
are updated to match and the orphaned screenshot is removed.
Introduce a status masthead above the node grid summarising fleet-wide
CPU, memory, container, and alert counts with a coloured rail that
reflects overall health. Pin the local node at the top of the grid with
a cyan accent rail and a Local badge so it is never confused with a
remote. Add a Topology view toggle that plots the local node on the
left with remotes radiating out, and colour-codes connector lines by
link health.
