/*
 * Gausser web funnel — signup, onboarding, account management.
 *
 * Every value here resolves to a custom property in tokens.css (the CSS binding
 * of DESIGN.md). The only literals below are geometry the token set does not
 * carry: letter-spacing values quoted from DESIGN.md typography, opacity, and
 * layout arithmetic. No colour is ever written as a literal — dark mode is
 * therefore automatic.
 *
 * NOTE ON THE `font:` SHORTHAND: it resets font-variant-numeric. Any rule that
 * uses `font: var(--type-*)` on a number must restate tabular-nums AFTER it.
