/* HYLTH marketing site — hand-written CSS for the static pages served at `/`.
 *
 * Every colour here is a custom property from tokens.css, which is generated
 * from src/theme/colors.ts (CLAUDE.md non-negotiable #2 — the palette is
 * locked and §9.1 is its source of truth). There are no hexes in this file,
 * deliberately. If you need a colour that isn't a token, amend §9.1 first.
 *
 * Two brand rules this file has to honour and which are easy to break in CSS:
 *   1. Never white-on-teal. The accent's foreground is always --on-accent.
 *   2. Teal is rare — one primary action per screen. This page has three
 *      audiences and therefore three calls to action, so exactly one of them
 *      (the AI coach CTA, and its repeat at the foot of the page — the same
 *      action, not a second one) is teal. The coach CTA is an outline button
 *      and the invite-code path is a text link. That hierarchy is the rule
 *      being obeyed, not a styling preference.
