/* Status page pubblica (/status) — insegna, quadro sinottico, aree.
 *
 * [STATUS-F3] a401545b-3675-44a8-9525-e84eaf836ffb: torna il quadro
 * ferroviario 2D (binari con casing agli incroci, etichette-linea stampate sul
 * binario, chip-stazione con lampada, hub ad anello), dentro la pagina ridotta
 * di [STATUS-F2] f743fd31: insegna con due numeri, quadro, aree in testo a
 * tendina. Stessi token della dashboard; destinatario opposto — un cliente,
 * non un operatore — quindi poche parole e niente legende.
 *
 * I token sono ricopiati da base.css invece che importati: questa pagina deve
 * poter essere servita da sola dietro un reverse proxy che proxa il solo
 * prefisso /status, senza trascinarsi dietro il design system del cockpit
 * (admin.css/layout.css portano con sé tutta la chrome operativa). Se i valori
 * divergono, quello giusto è base.css.
 *
 * Tema: SCURO e basta, come il quadro operativo. È l'identità del prodotto, e
 * una versione chiara sarebbe una diluizione di quell'identità, non una scelta.
