+- [x] `jury-fieldset.php` — WCAG 4.1.2: all "Externe" checkboxes (promoteur + each lecteur row, static + dynamically added via JS) now carry `aria-label="[Role] — externe"` providing group context without visible redundancy
+- [x] `jury-fieldset.php` — WCAG 2.1.1: jury remove buttons verified to have descriptive `aria-label="Supprimer le lecteur·ice N"` on all rows (static + dynamic)
+- [x] `admin.css` — added `.admin-body fieldset fieldset.admin-jury-lecteurs` rule: strips border/background on the nested lecteur fieldset so it renders as a visual sub-group, not a double-bordered card
+- [x] `todo/04-accessibility.md` — WCAG 1.4.4 + 1.4.12 audited and marked done: all font-sizes are `rem`; no `overflow:hidden` on essential text content

-- [ ] **Verify no text is set in `px`** — ensure `width: 14px; height: 14px` on checkboxes and similar elements do not prevent text scaling
+- [x] **Verify no text is set in `px`** — audited all CSS files; every `font-size` uses `rem` or `em`; no `px` font-size found anywhere. No action needed.
 
 ## 1.4.12 Text spacing
 
-- [ ] **No text-spacing override test done** — verify WCAG 1.4.12 bookmarklet does not cause content clipping (especially `overflow: hidden` on `.card__media` and tight `aspect-ratio: 4/3`)
+- [x] **No text-spacing override test done** — audited all `overflow: hidden` instances: `.sr-only` (visually hidden utility, 1×1px — not text content), `.home-body figure` / `aside figure` / `.card` (media containers, not text). `.card__gradient-title` clamps decorative gradient text — not essential content (same info is in the `<p>` link).

+- [x] **Admin jury "Lecteur·ices" label has no `for` attribute** — replaced plain `<label>Lecteur·ices :</label>` with `<fieldset class="admin-jury-lecteurs"><legend>Lecteur·ices</legend>` in `jury-fieldset.php`; CSS rule strips the nested fieldset’s border/padding so it renders as a sub-group
 
 ## 4.1.2 Name, role, value

+- [x] **Custom "Externe" checkbox for jury members has no group context** — all jury "Externe" checkboxes now carry explicit `aria-label` (e.g. `"Promoteur·ice — externe"`, `"Lecteur·ice N — externe"`); both static PHP-rendered rows and dynamically added rows via `addJuryRow()` receive the label
 
 - [ ] **`<video>` elements on `tfe.php` have no captions** — add `<track kind="captions">` slot in template; document caption requirement in admin upload form
 
 - [ ] **Admin `<select>` for visibility/access in `edit.php` uses truncated option text** — use full description in option text (or `title` attribute); keep truncated text only for visual display
 
-- [ ] **Bulk publish/unpublish JS does not announce result to screen readers** — add `role="alert"` to error messages and `role="status"` to success messages across all admin pages
+- [x] **Bulk publish/unpublish JS does not announce result to screen readers** — action result is a full-page redirect to a flash message rendered by `flash-messages.php` which already emits `role="alert"` (error) / `role="status"` (success); no additional JS announcement needed
