/* ---------------------------------------------------------------
   Adeia — Proof and Policy

   Two sections on the white ground. Proof stages the live ledger as
   a large panel with a --mist verdict card overlapping its lower
   right; Policy lays the four seed figures out as mono numerals
   separated by hairlines.

   Everything is scoped under .proof or .policy. Tokens and the shared
   classes (.label, .mono, .h2, .plus-link, .quiet) come from
   tokens.css and base.css and are not restated here.

   Outcome states never rely on hue to be told apart: executed is
   quiet and unmarked, held carries a solid edge marker, a fill, and
   the heaviest weight in the section, denied is struck through.
