/* Screwmaster storefront — design system
   Register: product/commerce (findability first), premium-but-simple.
   Scene: a joiner on a Tuesday, sawdust on the phone, needs the exact 35mm
   hinge found in three taps and out today. So: high legibility for specs,
   light workshop daylight, one confident accent, fast scanning.
   Colour strategy: restrained — cool off-white + near-black ink + one deep
   workshop green. Deliberately not Screwfix-blue, B&Q-orange, Toolstation-
   yellow, or the AI warm-cream default.
   Brand language: the hex bolt-head. It recurs as the family badge and the
   quiet accent, never as decoration for its own sake. */
