Approve-with-comments follow-ups (no blockers):
- callout: unify the GitHub-callout feature ticket on #192 (the callout-paste
feature the CHANGELOG already tracks); #218 is the public-share security work.
Fixed the code comment and test reference.
- export/utils.spec: pin current behavior of a leading-dot name (".gitignore" ->
"") — same bug class as #204 but unreachable via the sole caller, so document
not change.
- share.types: narrow ISharedPage to the actual /shares/page-info allowlist
(page -> Pick of id/slugId/title/icon/content; trimmed share; dropped the
spurious `extends IShare`). Verified all three consumers (shared-page,
link-view, mention-view) read only allowlist fields.
- editor-ext: extract shared CALLOUT_TYPES / normalizeCalloutType /
renderCalloutHtml into callout-common.marked.ts; both tokenizers
(`:::type` and `> [!type]`) now share the renderer + type dict while staying
separate. Eliminates the byte-identical renderer + duplicated type list.
- share.service: extract named predicate shareIdGrantsAccess(requestedShareId,
resolvedShare) for the id-or-key fast path (naming only, no control-flow
change); kept narrower than resolveReadableSharePage's id-only gate.
