/*!
 * ohm-ui-optimizer.css — mobile-first UI normalization + seamless-PWA layer + donation invite UI
 * for all tongue-analysis.com landing pages and the VERA/OHM PWAs.
 *
 * Two parts:
 *   1) A conservative global normalization that makes every existing page render well on phones
 *      (fluid type, ≥44px touch targets, safe-area insets, no horizontal overflow, PWA polish).
 *      It deliberately avoids restyling page content so it can't regress heterogeneous pages
 *      (some use Tailwind, some hand-rolled CSS).
 *   2) A fully namespaced (.ohm-don*) donation-invite sheet + roadmap that never collides with
 *      page styles.
 *
 * Design tokens mirror the existing suite: gold #d4af37, cyan #00D8FF, ink #0a0a0a.
