What

Published pages can carry a stamp region in their pinned markup, and workshop documents can embed a deliverables block that renders alongside decisions.

Details
  • The pinned-markup allowlist adds a stamp-control region delimited by <div class="stamp" and </div>, alongside the existing stylesheet and stale-banner regions.
  • Workshop deliverables render as <div class="ws-deliverables">.
  • Each deliverable carries a kind of pr, artifact or other, with links, parsed out and surfaced next to decisions.
