Commit A lands a lasting navigation design: ItemId browse_href/from_browse_uri (with https:/ normalization and tests), a /~/ route, and call-site cleanup—plus real simplification by dropping the theme cookie/CSS stack. Commit B is valuable consolidation (fold web_post into POST /ui, WebSession, form __rpc__ migration) but mostly relocates existing ingest/check/redact behavior rather than adding comparable core design.
