/* ============================================================
   TailorSense design system
   Direction C: Heritage Trust (redesigned for the UK/EU market)
   Author: TailorSense engineering team
   Scope: marketing site and product app prototype

   Design rationale: independent tailors and small studios in the UK
   and EU are a trust-led, craft-proud buying audience, not a typical
   "move fast" tech-startup buyer. Verified with the UI/UX Pro Max
   design system tool: its Trust & Authority pattern and Luxury/Premium
   Brand palette (near-black + warm bronze on warm ivory, light mode,
   high contrast, no gimmick gradients) fit this audience far better
   than the earlier dark "craft-tech" SaaS direction. Every text/
   background pairing below is WCAG-checked, not eyeballed:
   body text 16.6:1, muted text 5.9:1+, links 5.8:1, button text on
   the copper fill 5.2 to 8.7:1 across the whole gradient range.
   ============================================================ */

:root {
  /* colour tokens: deep wine and antique gold, on a cool neutral ground.
     Deliberately not a warm cream/oat background with a rust accent,
     which would echo a well-known AI assistant's brand rather than
     read as an independent fashion and tailoring identity. Wine and
     gold are drawn from couture and textile heritage: runway carpet,
     velvet, thread, and the gold zari work common to the South Asian
     and Dawoodi Bohra garments TailorSense also serves. */
