   Pevra Humaniser — writing command deck

   Same language as chat's command deck: Pevra tokens, display type for
   empty states, Geist Mono kickers, an ember spine on what you wrote,
   the rewrite as the card. Nothing here restyles a shared class — every
   rule is #view-humaniser or .hm- / #hm- — so Codex and Claude's chrome
   cannot be moved by this sheet.

   Desktop fills the view. Editors scroll. The page does not.
   Motion is scoped here too: enter, busy, land, reduced-motion.
