 * Thistle #D7BED7, testo Raisin Black #212121, sfondo Ghost #F9FBFD.
 * Tipografia: Suranna (serif, titoli) + Montserrat (body).
 *
 * I colori e l'URL del logo arrivano da :root iniettato inline dalla classe
 * Learn_O_Studio_Login, cosi restano sovrascrivibili per-tenant via filtro.
 * Qui i valori sono solo fallback di sicurezza.
