/*
 * kainet-ui.css — ONE shared component + motion layer for the dev templates.
 *
 * Tokens and components are the Mint SaaS design kit (templates/design_kit.md)
 * as CSS: tonal surfaces instead of 1px borders, gradient primary CTA, system
 * font stack, soft ambient shadows. Motion is native and cheap: cross-document
 * view transitions, one entrance animation, hover lifts — all killed by
 * prefers-reduced-motion.
 * WHY: 48 templates carry drifting copies of these tokens; a page that
 * imports this file instead stays cohesive with every other adopter for free.
 * Adoption rule: any template you touch imports this + the unified shell in
 * the same change (see design_kit.md §9).
