/* =========================================================================
   Bumrungrad International Hospital — Phuket
   Corporate Identity palette, modern "liquid glass" UI language.

   CI notes honoured in this stylesheet:
   - Composition stays 60–70% white / off-white; CI colours are used only as
     accents (headings, icons, CTA, thin dividers, footer swatches).
   - No embossing, drop-shadow illustration, or colour gradients are used on
     brand marks, headings, or flat surfaces.
   - The single translucency/blur affordance ("liquid glass") is treated as a
     modern *UI chrome* material (pills, cards, nav) rather than a graphic
     treatment of the logo or CI colours themselves — kept intentionally
     restrained (soft blur + 1px hairline + faint elevation only).
