Patch release for resilient mailbox HTML parsing.
- Fixes a scan crash when a hidden styled HTML container contains styled descendants.
- Processes destructive DOM snapshots descendant-first so decomposed ancestors cannot invalidate later nodes.
- Converts bounded HTML parser/data-shape failures into privacy-safe per-message rejections, preserving partial-scan behavior.
- Preserves hidden-content filtering, visible HTTP/HTTPS link extraction, parser bounds, local storage, and the exact Gmail read-only scope.
No OAuth, provider, database, installer, website, or privacy architecture changes are included. The live installer remains pinned to v0.1.3 until the separate verified installer-pin change is merged.
