/* ============================================================
   Landing page. Same design language as the www marketing site
   (marketing/src/styles/global.css): warm gunmetal darks, brand
   teal, amber accent, Archivo display + IBM Plex Sans.

   CONTRAST, measured against the WCAG ratios, not eyeballed:
   - Filled buttons are DARK INK ON BRIGHT TEAL (#0e1512 on #19c2ad,
     ~8:1). White on the brand teal #03a18d is only ~3.3:1 and fails
     normal-size text, so it is never used for button labels.
   - Muted text on white is #6b6457 (~5.8:1); the www token #877f70
     is ~4:1 and fails small text, so it is not used here.
   - Amber is only ever used ON DARK (#ef8a3c on #15181c ~7:1).
