/* ==========================================================================
   Basin — social-bathhouse / contrast-therapy template
   A Templatorium template · https://templatorium.com

   HOW TO RE-THEME (the 30-second version — full guide in docs/README.md):
   every colour, font, and size the design uses is a custom property in the
   :root block directly below. Change the values there and the whole site
   follows. Everything under the tokens is structure; you rarely touch it.

   The signature is a CONTRAST BATH: as you scroll, full-bleed temperature
   bands alternate hot (Ember) and cold (Plunge), and the text colour flips
   light/dark across each steam-seam. The bands are plain CSS grounds, so the
   page renders complete with JavaScript switched off.

   A promise this template keeps: every text/background pair in the shipped
   palette meets WCAG 2.2 AA (computed, not eyeballed — the worst real-text
   pair is 4.5:1). Re-check any colour you change:
