   CHARACTER HISTORY (ADR-0043)
   A full-screen pushed layer over the community overlay: list -> version.
   Composed from the sub-screen family (.sub-bar + .glass-chip + .large-title +
   .settings-screen), ledger rows (.settings-row.has-tile), media row tiles
   (.ci-tile), disclosure folds (.fold-pick) and scenario cards (.scenario-pick).
   Only the diff marks and the layer geometry are new. Tokens only.

   happens and a thumb of a 2000px photo sat as a small frame in the middle of a
