/* CrossBorder Care · platform demo · visual language of concept B ("Locomotive")
   One deep teal-ink ground for the shell chrome, one warm paper for everything people read, one luminous
   amber accent for the primary action and "you are here" markers. No external assets (mainland-China safe).
   Motion: expo-out, transform and opacity only, and only when something actually changed (the shell marks
   persona switches with .is-entering and changed chips with .chip-flip). Reduced motion gets a still page.
   Component classes used by views (via ui.js): card, kv, list/row, chip-*, btn-*, next, notice-*, tabs, field,
   input, check, progress, thread, json, empty, grid-2, grid-3, stack, compare, muted, small, money. */
