@ -10,6 +10,7 @@ The format follows *Keep a Changelog*. Versions use semantic versioning with pre
- Stabilized first-open rendering from the project sidebar so file content and syntax highlighting appear on first click without requiring tab switches.
- Hardened startup/session behavior so `Reopen Last Session` reliably wins over conflicting blank-document startup states.
- Refined large-file activation and loading placeholders to avoid misclassifying smaller files as large-file sessions.
- Added Share Shot (`Code Snapshot`) creation flow with toolbar + selection-context actions (`camera.viewfinder`) and a styled share/export composer.
### Fixes
- Fixed a session-restore regression where previously open files could appear empty on first sidebar click until changing tabs.

- Added a dedicated large-file open mode with deferred first paint and chunked text installation, so ultra-large files no longer depend on a single blocking initial render.
- Added per-session large-file modes directly in the editor UI: `Standard`, `Deferred`, and `Plain Text`.
- Added clearer large-file status chrome with line counts and session indicators in the editor/status surfaces.
- Added Share Shot (`Code Snapshot`) workflow with the toolbar `camera.viewfinder` action and an export/share composer.
- Fixed large-file responsiveness regressions across project-sidebar reopen, tab switching, and status updates.
- Fixed large-file editor stability issues around line-number visibility and blank/flickering content during heavy-file workflows.
