+## Support website-type TFE (URL instead of uploaded files)
+- [x] Add `file_type = 'website'` support to `thesis_files` — URL stored in `file_path`, no filesystem upload (no schema change needed)
+- [x] Admin add form: "Site web (URL)" field dynamically shown via HTMX when "Site web" format checked
+- [x] Admin edit form: website URL field via HTMX toggle + recognize website (🌐 icon) in existing-files list
+- [x] Student partage form: website URL field via HTMX toggle + HTMX script added
+- [x] TFE detail page (`tfe.php`): render `website` type as iframe with sandbox in media section
+- [x] `ThesisCreateController`: handle website URL in submit → `handleWebsiteUrl()` stores as thesis_files row
+- [x] `ThesisEditController`: handle website URL in save → `handleWebsiteUrl()` replaces existing website row; delete-files skips unlink for URLs
+- [x] Edit page: website rows deletable via same delete_files checkbox mechanism
+- [x] File size 0 for website rows — hidden in edit list to avoid showing "0.00 MB"
+- [x] HTMX fragment endpoint: `/admin/actions/format-website-fragment.php` + `/partage/format-website-fragment`
+- [x] `checkbox-list.php` partial: optional `hxPost`/`hxTarget` for HTMX live update
+- [x] Server-side initial render: pre-populate `#website-url-section` if "Site web" already checked
