/* RollStill AI Assistant landing page. Colours are the Doorway page's (door.css), which passed the 10/21 WCAG 2.2 AA
   contrast check: --accent is for text and links on the dark page, white button text sits on --accent-fill. System
   fonts only (no outside fonts). The orb is Mercury 3D, RollStill's default (10/30): a still picture drawn by the
   site's orb.js (mercury.webp and mercury-sm.webp, made by tools/orb_stills.cjs) in the header and on pages without
   scripts, and live on the landing page (orb.js). It holds still for people who ask for less motion. */
