   rehaul-reference.css
   Visual + motion rehaul for the iOS reference screens and the cocktail finder:
     Bottles · Glassware · Colour Codes · Bar Codes · What can I make?
   Owned by the reference-screens agent. NEW classes only, all prefixed `bkr-`.
   Reuses shared tokens (--ease-out, --dur-*, --surface, --line, --fg-*) and
   shared classes (.bk-empty, .bk-chip, .ios-photo-card, .ios-colour-pill …).
   Only transform/opacity is animated; the global prefers-reduced-motion block in
   colors_and_type.css neutralises every animation/transition here automatically.
   British spelling, no em dashes, no emojis.
