   white wedge below the inbox tail message. On the DM page we want it to
   match the inbox list's gray (--surface-app) so the panel reads as one
   continuous surface. Scoped to body.dm-page so Shop/Backpack/etc. drawers
   are unaffected.

   9c. VIEWPORT LOCK (all sizes)
   The DM page owns its chrome and must pin the composer to the bottom of the
   visible viewport — no gray slack below the input. Lock the whole shell-to-
   conversation chain to 100dvh so the flex column inside .dm-conversation
   (messages flex:1 → dock) always anchors at the screen bottom regardless of
   viewport height. (Promoted out of the mobile media
   query 2026-06-17 — Steven flagged the composer floating high on desktop.)
