/* ── unlock scroll story ──────────────────────────────────
   A sticky iPhone on a night band. Scrolling down: the Liquid Glass lock
   screen recognises you (the padlock opens), slides away, Silo's own app lock
   clears, and Home is there. home.js drives --p (whole story), --u (lock
   screen away) and --v (app lock away). The lock screen is drawn in CSS: a
   likeness of iOS's, not an Apple asset; its clock uses the visitor's system
   font, so on an iPhone or a Mac it is Apple's own. */
