## Summary by CodeRabbit
* **New Features**
* HTML import now splits lines on <br> into separate paragraphs while
preserving inline formatting.
* **Bug Fixes**
* Paste falls back to inserting after the first paragraph when no
explicit target is found.
* **Style**
* Improved page-mode viewport styling for consistent content layout.
* **Tests**
* Added snapshot tests for <br>-based paragraph splitting; re-enabled an
e2e drag-page test.
* **Chores**
* Deferred/deduplicated font loading, inline text caching,
drag-handle/pointer optimizations, and safer inline render
synchronization.
