Two verified gaps from parity wave 3 (PR #410) + the 2026-07-24 audit: PagePreview slots implement none of docs/features/card-dom-api.md (no data-card-*, no mpc:card-selected), and no per-slot next/prev image cycling exists on the sheet (E24 corner reserved, backside toggle entering the design round separately). External tooling built on the DOM contract gets nothing on the unified page.
