/* ==========================================================================
   Pagina Kart, blocco unico "Scegli il tuo kart" (richieste v4, T3 e 20/10):
   configuratore nel pannello scuro del selettore, impaginato come una scheda
   prodotto (esempio Canyon) e tutto dentro lo schermo da desktop
   (t4-config.js, montato da t4-kart-select.js dentro .t4ks__panel)
   - .t4cf             radice nel corpo del pannello (step, modulo)
   - .t4cf-step--inline step obbligatorio sempre aperto (taglie, consegna)
   - .t4cf-rows        "Accessori e servizi": righe compatte, una aperta alla volta
   - .t4cf-opt         tessera di opzione (vetro scuro, bordo azzurro quando scelta)
   - .t4cf-foot        piede fisso del pannello: totale con le voci, bottone di stato
   - .t4cf-form        modulo di preventivo (prende il posto degli step)
   Token e .t4-pill da t4-fx.css. Misure in px: la root del tema cambia valore
   con la larghezza. Movimento solo dentro (prefers-reduced-motion: no-preference).
