 * Thier — marketing site design system
 * v2 — 2026-05-08 rebuild
 *
 * Tokens are derived from the iOS app's `SpanTheme.swift`:
 *   primary teal (0.06, 0.58, 0.54)  → #0F948B
 *   accent amber (0.98, 0.72, 0.22)  → #FAB838
 *   secondary lavender                → #9F85EB
 *   ink (deep ink, primary text)     → #0B1A1A
 *
 * Typography is the system font stack (-apple-system / SF Pro
 * Display) which matches the app exactly on iOS and gives
 * native-feeling text on every other platform.

   reset, the HTML `hidden` attribute (which is supposed to be
   equivalent to `display: none`) gets overridden by the more-
   specific class rule, and every state section renders at the
   same time. Symptom: "Couldn't load your home" error card
