v0.3 Phase 3: status grammar — LumotiaNotice left-bar refactor

Phase 3 audit found that both LumotiaStatusPill and LumotiaNotice
already shipped in v0.2 Phase 5. Phase 3 reduced to an audit-and-adapt
pass.

LumotiaStatusPill ($lib/components/StatusPill.svelte) is already
correct for quietware. Pattern: neutral pill background + neutral
label text + role colour confined to a 6x6 px dot. Colour is
supplementary, label is always perceivable. Works unchanged across
all three quietware modes. No changes shipped.

LumotiaNotice ($lib/ui/LumotiaNotice.svelte) refactored to the
left-bar accent pattern. Previously the role colour rendered on the
icon outline and on the entire surround border at 30% opacity; in
quietware light mode that left the bright #FFCD00 caution colour
faded against cream paper. New pattern:

  - 4-px solid LEFT border in the tone colour, 100% opacity.
  - Soft tone-tinted background (10% opacity) for ambient cue.
  - Subtle neutral outer border on the other three sides.
  - Icon, title and body text all use --color-text.

Visible signal lives on the large bar (works at any contrast level);
foreground text uses the always-legible neutral. Matches Material
Design "banner with leading accent" and IBM Carbon "inline
notification" guidance. ARIA semantics (role="alert" for danger,
role="status" for the rest) preserved.

Design-system-v2 preview route already imports both primitives. The
updated Notice renders correctly with the existing preview content;
no additional wiring required.

Caution remains a fill-only convention on cream by design. Any
darkened yellow reads as olive ("looks like poop", per Jake), so the
fill-only rule stays in force and this pattern delivers it cleanly.

+Architectural finding: both `LumotiaStatusPill` and `LumotiaNotice` already shipped in v0.2 Phase 5. Phase 3 became an audit-and-adapt task rather than a new-component build.

+- `LumotiaStatusPill` ([src/lib/components/StatusPill.svelte](../../src/lib/components/StatusPill.svelte)) audited. Pattern is already accessibility-correct: neutral pill background + neutral label text + role colour confined to a 6×6 px dot. Colour is supplementary, label is always perceivable. Works unchanged across all three quietware modes. No changes shipped.

+- `LumotiaNotice` ([src/lib/ui/LumotiaNotice.svelte](../../src/lib/ui/LumotiaNotice.svelte)) refactored to the left-bar accent pattern. Old version put the role colour on the icon + outline; in quietware light mode that rendered a bright `#FFCD00` caution icon faded against cream paper. New version places the role signal on a 4-px solid left border (visible at any contrast level), with the rest of the surround as a soft tone-tinted background plus subtle neutral outer border. Icon, title and body text all use `--color-text`. Matches Material "banner with leading accent" and IBM Carbon "inline notification" guidance. ARIA semantics (`role="alert"` for danger, `role="status"` for the rest) preserved.

+- Design-system-v2 preview route already imports `LumotiaNotice` and `LumotiaStatusPill`. The updated Notice renders correctly there with the existing preview content; no additional preview wiring needed.
+
+- All four tones (info / caution / danger / success) verified by the pattern itself: the visible signal is the left bar, which is `border-l-{tone}` at 100% opacity, working at any colour intensity. Caution remains a fill-only convention on cream by design.
