/* Home and products (decision 0005, restart): the hero variants, the four doors, the shop's-day story, the ecosystem
   map and the tilt cards. Loaded after styles.css on the home page and the products page only; it uses the tokens of
   styles.css (colours, --step-*, --space-*) and logical properties only (RTL mirrors by itself).

   Motion rules: everything is complete and readable without any animation. Scroll-driven animation
   (animation-timeline) lives ONLY inside @supports (animation-timeline: scroll()) AND
   @media (prefers-reduced-motion: no-preference); elsewhere (older browsers, reduced motion) the static state shows.
   No inline style anywhere: the small scripts in site.js only set CSS custom properties through the CSSOM. */
