/* Orion Residence subpages, in the homepage's own world (src/index.css): the tower at blue hour.
   Bone stone ground, blue-black night ink, one restrained bronze from the lit facade; Noto Serif light for every
   heading, Hanken Grotesk for text, Noto Serif/Sans SC for Chinese. Hairline rules instead of boxes; night panels
   only for the photo hero, the level directory, the map frame and the closing band, as on the homepage.
   Structure follows the Ren / CloutHaus subpages: photo hero with figures, ruled tables, plan sheets, FAQ, photo CTA. */
