/* ============================================================
   BUREAU OF LOST TIMELINES — SYSTEM ARCHIVE SHEET
   Version: 2.0 (Dossier system)

   backup.html is the records office of the Bureau: it counts what the
   device is holding and moves it in and out as paper. The page is
   therefore mostly ink and red, with exactly one green moment — the
   storage census, which is a machine reading its own memory. The
   import well is where untrusted JSON is described back before being
   applied, so its summary is a printed manifest, not a chat bubble.

   Colour, size and spacing come from css/tokens.css. No hex values,
   no emoji: destructive blocks are marked by a hazard stripe, the gate
   by a seal plate.
