Parity seams for hosts of @plannotator/ui, requested by Workspaces after the HTML annotation handoff: projectHostThreads and buildPersistedHtmlAnchor in @plannotator/core; HtmlViewer onUnanchoredChange completed over the annotations prop with a restore-keyed report so hosts can drop their mark-applied listeners; published useHtmlRefresh with a fetchSnapshot adapter; published HtmlSurfaceControls (eye, refresh, pen) with label overrides; AnnotationPanel unanchoredIds chip (wired for Plannotator too); HtmlViewer maxAdditionalTargets and scrollBehavior carried on the bridge; shortcuts and utils/inputMethod blessed as consumer exports. Plannotator's behavior is unchanged apart from the new Unanchored chip, verified by a real-browser A/B including the orphan and re-anchor cycle and by a combined cross-surface verification with #1394.
