SHARD-WP-0003 T6. Enterprise document-collab contrast to Notion: a doc +
spreadsheet hybrid where a page is prose interleaved with embedded live
structured objects (spreadsheets, kanban/calendar live apps), reachable only by
REST with HTML import/export (lossy to Markdown), gated by Salesforce
identity/ACL. Generalizes external-API mode with an HTML payload-format facet
(beside Notion block-JSON, Wiki.js GraphQL); pushes page model toward
inline embedded structured objects. UC-80. Enriched UC-57/55/58/36/06. Marks
T6 done. Feeds SHARD-WP-0002 T11/T12/T14.
