/* Le climat à Ferooz — page publique (SPEC §5).
 *
 * Identité visuelle reprise de OpenHABFeroozLight/html/temperature-dashboard.html :
 * mêmes variables de thème, mêmes cartes, mêmes chips, même infobulle. La page
 * publique ressemble donc aux pages internes du domaine, ce qui est le
 * résultat souhaité (SPEC §5.1).
 *
 * Fichier séparé — et non style en ligne comme les pages internes — pour une
 * raison unique : la CSP stricte de §7 interdit 'unsafe-inline'. Un fichier
 * autorise style-src 'self', qui est robuste ; des hachages SHA-256 seraient
 * à recalculer à chaque modification et cassés au premier oubli (SPEC §5.2).
