 ## Recently completed (this session)
 
+- [x] `admin/thanks.php` + `admin/pages.php` + `admin.css` — extracted last 3 inline `style=` attributes from admin PHP templates: `<div style="margin-top:1.5rem;display:flex;gap:.75rem;flex-wrap:wrap;">` in `thanks.php` → `class="admin-action-bar"` (`.admin-action-bar` rule added to CSS); `<p style="color:var(--text-secondary);">` in `thanks.php` → `class="admin-muted"` (`.admin-muted` rule added); `style="font-size:.8rem;padding:.3rem .75rem;"` on Éditer button in `pages.php` → `class="admin-btn admin-btn--sm"` (uses existing modifier). Only the dynamic `--disk-pct`/`--disk-color` CSS custom properties on the disk bar in `system.php` remain (carry PHP runtime values — legitimate).
+
 - [x] `variables.css` + `search.css` — public dark-mode support via `@media (prefers-color-scheme: dark)` scoped to `body:not(.admin-body)`: all semantic tokens (`--bg-*`, `--text-*`, `--border-*`, `--accent-*`, status colours) overridden with dark equivalents; `--accent-primary` lightened to `#b87fd4` for WCAG contrast on dark backgrounds; `--search-error-*` variables added to replace hardcoded `#fff0f0`/`#c00` in `.search-error`; admin pages unaffected
