Polish items deferred out of v0.18.0 once that release narrowed to the rune-contract hardening (SPEC-081/082) plus the legacy slots + structure shim removal (WORK-313).
Lumina's CSS references several colour tokens that are never defined, so each paints a stale literal fallback (a sky-blue from an old default theme, or a cool Tailwind gray) that doesn't track light/dark. This is the real cause of the "out of place" blue (e.g. the typography specimen background) and the cold-gray muted text in dark mode. Fix the drift at the source, reconcile the vocabulary, and keep the configurable shapes (presets, generator, docs) in correspondence.
Make dark-mode token coverage deliberate. Most "dark looks off" reports trace to the phantom tokens fixed in WORK-340 (a phantom can't have a dark value); this item closes the genuine remaining gaps and records the intentional shared-token decisions.
Accessibility polish across the theme. Today only ~5 of ~90 rune CSS files define :focus-visible, and only 2 honor prefers-reduced-motion — so keyboard focus is inconsistent and animations don't degrade for motion-sensitive users.
