/* ══════════════════════════════════════════════════════════════════════
   空の間 — Sora's Corner. A ledger, first person.

   Sits on the shared palette in css/yamero.css and the self-hosted faces in
   fonts.css; only what is particular to this room lives here. The room's one
   idea: the tank is the archive. Each entry is a creature in it, and the water
   fills as the ledger does — so a page with two entries looks like a page with
   two entries, and in five years it will look like five years.
