/* ==========================================================================
   TMA Microsite Platform — design system
   Rebuilt to match the Claude Design homepage direction.

   Key moves from the Design render:
   - Full-bleed arch hero: the photo sits behind a tall arch, headline overlaps.
   - Warm sand hero band and lavender-tinted evidence band; navy stat band.
   - "Is this you?" symptom grid with small dot markers, not numerals.
   - Generous whitespace, restrained type sizes, pill buttons, soft shadows.
   - Palette and fonts unchanged from the practice brand.

   Non-negotiables preserved: footer disclaimer visible on every page, both
   credential badges distinct (BHRT TA certifies, TMA is membership), reference
   tier chips retained, AA contrast throughout.
