/**
 * Grovio — shared web styles (v2.0 redesign)
 *
 * Mirrors the v2.0 iOS / iPad app design language:
 *   - Warm near-black palette (#161616 page, #1F1F1F surfaces)
 *   - Single brass-yellow accent (#FFB800) — replaces the prior cobalt
 *   - Display: Archivo Black; Body: Hanken Grotesk (Google Fonts)
 *   - Engraved badge letters (brass-on-warm-stone) — matches the app's
 *     BadgeMedallion textShadow recipe
 *   - Punched/recessed effects via inset box-shadow on slots & tracks
 *   - Raised cards with stronger drop shadows for depth
 *   - Dark-only — no light-mode override (matches the dark-only product
 *     decision shipped in the app's ThemeProvider)
