/* HistoryShowcase marketing pages: a museum of school history. A dark forest entrance hall opens
   through an engraved arch into lit limestone rooms, each signed with a Roman gallery number.
   Text pairings meet WCAG 2.2 AA (4.5:1) on their surfaces. Lit rooms: ink 13.9, ink-soft 7.8,
   ink-muted 5.3 and accent 6.4 on limestone (4.7+ on its deeper tint). Dark rooms: ivory 15.8,
   ivory-soft 9.4, ivory-muted 5.8 and brass 8.8 on the entrance; forest on brass 6.3+. After hours:
   ink 14.0, ink-soft 9.3, ink-muted 7.0 and accent 9.8 on the dimmed walls. */
