/* ══════════════════════════════════════════════════════════════════════
   pharma.css — the Sigma-Audley pharmaceutical frontend, merged into the
   shop engine.

   EVERYTHING is scoped under .ph so it can never clobber the engine's
   global.css / home.css or the identity layer. The engine owns the hero,
   trending grid, cart/checkout modals, warehouse modal and FAQ — those are
   untouched, because their IDs and classes are a live JS contract.

   Colours are taken from the shop's own identity ramp so this reads as one
   site, not a graft: crimson #CC2631 primary, warm-paper surfaces, ink text.
   All pairs clear WCAG AA (contrast-audit.js exit 0).
