/**
 * MINOMO — Guest Onboarding (welcome screen + città picker)
 * app.minomo.io · /app.html (guest, primo avvio)
 *
 * Wave GUEST-ONBOARDING · 2026-07-14.
 * Visual reference approvato da Vito (mockup interattivo, poi rimosso dal
 * repo prima del commit). Riusa i token di minomo-2026.css (--bg, --card,
 * --text, --orange, --logo-grad, ecc.) — nessun colore hardcoded fuori
 * scala salvo dove il mockup lo richiede esplicitamente (glow ambient).
 *
 * Convenzioni: `.ob-*` = onboarding-only (welcome overlay + city sheet,
 * riusata anche dal chip GUEST-ONLY in Home tramite openCityChangeSheet()).
