Interlace Theme

The three entry animations in styles/theme.css now run at 200ms with no delay, and the reduced-motion class list in styles/tokens.css covers .animate-pulse. .animate-fade-in-up was 0.5s, .animate-slide-in-left 0.5s behind a 0.3s delay, and .animate-scale-in 0.4s behind a 0.2s delay — up to 800ms before the reader saw anything, against the 200ms entry ceiling MOTION_PHILOSOPHY.md has always set. All three are now 0.2s ease-out both. The delays were the worse half: an entry animation is already laid out at opacity: 0, so a delay is time spent looking at nothing. Separately, .animate-pulse — the animation Skeleton renders on every loading state — was missing from the tokens.css reduced-motion list, along with .animate-meteor and .animate-meteor-effect. The universal clamp in styles/preflight.css was already covering all three, so apps importing styles/index.css were never affected; apps that import tokens.css and theme.css à la carte and skip preflight.css were. All three are now listed. Both are held by packages/ui/__tests__/motion-contract-lock.test.ts, which reads the ceiling out of MOTION_PHILOSOPHY.md rather than repeating it, and fails if any bare animate-* utility in packages/ui/src is missing from the list.

The brand layer is forkable: the whole palette moved from Tailwind violet to the burnt-orange/green Interlace palette inside @layer interlace.brand with zero component edits, and the CSS baseline ships as one installable theme item — tokens, foundation, preflight (WCAG 2.2 SC 2.4.13 focus ring and the [data-min-viewport] contract), the shadcn↔fumadocs bridge, and the brand palette.
