/* ════════════════════════════════════════════════════════════════════
 * GPX-Tool — Design System "Komoot-style"
 * v1.0 — Apr 2026
 *
 * Filosofia:
 *  • Mobile-first, touch target ≥ 44px
 *  • Card pulite con bordi sottili, ZERO ombre forti
 *  • Tipografia bold per i numeri (statistiche), label MAIUSCOLE piccole
 *  • Bottom nav fissa stile Komoot
 *  • Brand color = arancio Strava #FC4C02 (decisione Paolo: arancio resta primary)
 *  • Palette neutra warm-grey
 *
 * Convenzione classi:
 *   .gx-*     = nuovi componenti del design system
 *   .card etc = ristilizzati in-place per non rompere JS hooks
 * ════════════════════════════════════════════════════════════════════ */
