nx_brand_polish.nx

nx_brand_polish.nx -- R7 visual polish: a token-driven MOTION language + MICRO-INTERACTIONS, emitted as pure CSS (zero JS) and wired into the builder's <style>. Motion uses the brand's motion tokens (var(--nx-motion-fast/ease)) so it re-themes with the brand; hover/active/focus states give interaction feedback; focus-visible rings use the accent token (accessible + on-brand). ACCESSIBILITY BY CONSTRUCTION: all movement is wrapped in @media(prefers-reduced-motion:no-preference) so motion-sensitive users never get it. HONEST SCOPE: this is the polish MECHANISM -- the subjective "world-class look" remains human-judged (R6 reports that axis as BEHIND). Library, no main; emits to an fd with its own writer (no nx_web_builder dep -> no import cycle). 100% sovereign. license_tier: ORIGINAL
