/**
 * Landing pubblica di A11yPilot.
 *
 * Sta in `public/` e non passa dal bundle: e' una pagina di marketing, e non
 * deve trascinarsi dietro Firebase, App Check o reCAPTCHA. Chi la apre non ha
 * un account e non deve essere attestato per leggere che cosa fa il prodotto.
 *
 * Palette e font sono quelli dell'applicazione (tokens.css), perche' chi passa
 * di qui all'accesso deve trovare lo stesso prodotto e non un secondo marchio.
 *
 * Una pagina che vende audit di accessibilita' non puo' permettersi di
 * fallirne uno: landmark dichiarati, skip link, contrasto verificato, focus
 * sempre visibile, nessun testo affidato al solo colore, animazioni che si
 * spengono con prefers-reduced-motion.
