/* Forge Fitness — useforgefitness.com
 *
 * The palette and the typeface are the APP'S OWN (Manrope, Forge blue,
 * and the meaning colours from AppStore.swift's adaptive tokens), so the
 * site reads as the product rather than as marketing about it. The
 * meaning colours — sleep purple, heart red, streak orange, PR gold —
 * are used only where they mean what they mean in the app.
 *
 * Every colour is a token on :root, redefined for dark twice: once
 * behind prefers-color-scheme (guarded so an explicit light choice
 * wins), once behind [data-theme="dark"].
