Three additions land together so the slider is meaningful from day
one (instead of recording a preference that nothing consumes yet).
Static grain overlay.
- src/design-system/v0.3-quietware-tokens.css adds a fixed-position
body::after element that ships an SVG feTurbulence noise tile
repeated across the viewport. Opacity reads from
--quietware-texture-opacity. mix-blend-mode: overlay produces the
soft notebook-paper feel without obscuring content.
- pointer-events: none so clicks pass through. Active only under
html[data-design="quietware"]. High-contrast forces opacity to 0
via the existing HC palette block.
QuietwareAccessibilityControls component.
- NEW: src/lib/components/QuietwareAccessibilityControls.svelte.
Two controls, both quietware-only:
1. High-contrast toggle wires html[data-contrast="high"].
Overrides the OS prefers-contrast: more query when explicitly
on. Built on LumotiaToggle so it inherits the accessible
label + description pattern.
2. Texture-intensity slider, range 0.05 to 0.08, step 0.005,
default 0.06. Sets --quietware-texture-opacity inline on
<html>, overriding the per-mode default in the tokens CSS.
Disabled while high-contrast is on. Reset button restores
0.06.
- Persistence: localStorage keys
lumotia:quietware:high-contrast
lumotia:quietware:texture-opacity
so choices survive dev rebuilds and full restarts. Full
integration with the central Preferences store is a follow-up;
localStorage keeps Phase 4c contained.
SettingsPage Accessibility section.
- Imports the new QuietwareAccessibilityControls component.
- Renders {#if isQuietware} <QuietwareAccessibilityControls />
{/if} immediately after the existing AccessibilityControls block.
- Search filter copy extended to cover the new control vocabulary.
Verified.
- npm run check: 0 errors, 0 warnings across 5706 files.
