+## Refactor form structure per spec (student vs admin)
+- [x] Remove `jury_president` field from student-facing forms (edit keeps it as optional)
+- [x] Jury: split into promoteur·ice interne, promoteur·ice ULB, lecteur·ice interne, lecteur·ice externe — each with +add button
+- [x] AP filtering: student form hides PACS; admin form shows all APs
+- [x] Language: add "autre" text field alongside predefined checkboxes
+- [x] Duration: split into pages field + minutes field + annexes checkbox
+- [x] Licence: removed from métadonnées fieldset, now only in degrés d'ouverture section
+- [x] Degrés d'ouverture: généralités FIRST, then radio choice (Libre/Interne/Interdit), then licence dropdown + custom text + CC2r
+- [x] CC4r → CC2r rename in form UI + `cc2r` POST name
+- [x] Licence: custom licence text field added (`license_custom` DB column)
+- [x] Généralités text editable via form help block (`fieldset_generalites`)
+- [x] Libre option: hidden in student form when disabled in settings; always shown in admin
+- [x] Contact: `contact_visible` field always present in TFE info; admin gets `contact_public` checkbox separately
+- [x] Email confirmation: mandatory in student form, optional in admin
+- [x] Fichiers: cover image hint updated to 4:3 ratio
+- [x] All three form pages (admin add, admin edit, partage) updated
+- [x] Controllers updated: `collectJuryMembers`, `validateAndSanitise`, `buildFileSizeInfo`, `license_custom`, `cc2r`→`cc4r` mapping
