/* ============================================================================
   MUZAFFAR TYRES — design system
   ----------------------------------------------------------------------------
   Ground:  graphite, the colour of the product itself. Warm off-white in light
            mode - a rubber-dust neutral, never a clinical pure white.
   Accent:  amber, one bold colour only, borrowed from road marking and hazard
            tape. It marks the single next action on a screen and nothing else.
   Type:    Barlow Condensed for headings (a grotesque drawn from transport
            signage - the right register for freight), Barlow for reading, and
            IBM Plex Mono for sizes and ply ratings, which are part numbers and
            should line up in a column like part numbers.
   Motion:  everything is CSS transitions driven by class toggles. Nothing here
            depends on requestAnimationFrame, so a backgrounded tab can never
            strand content invisible.

   A buyer looking at 32 tyres in one size has no way to hold three of them
   side by side, and no way to ask for a price on more than one at a time.
   The tray follows them across the catalogue, opens into a spec comparison,
   and turns straight into a single quote for everything in it.
