/* RareBill brand stylesheet — static marketing + legal site (Cloudflare Pages, zero build).
 *
 * Brand tokens mirror App/RareBill/Design/Theme.swift:
 *   ink      #070810   near-black canvas; the app is dark by design
 *   gold     #FAC742   JACKPOT accent — the star note, and the brand colour
 *   mint     #3DDB99   WORTH KEEPING
 *   violet   #996BFA   RARE FIND
 *   slate    #8C99B3   FACE VALUE
 *
 * Dark-first, because the app is. Light mode swaps gold for a bronze dark
 * enough to stay legible on paper-white — gold on white is 1.7:1 and fails.
 * Typography: the native Apple stack, so the web feel matches the in-app feel.
