CSS: .site-search → header form[role="search"],
.site-search__icon → header form[role="search"] svg,
.site-search__input → header form[role="search"] input,
.site-search__input::placeholder → header form[role="search"] input::placeholder
HTML: Removed class="site-search", class="site-search__icon", and
class="site-search__input" from header.php and search-bar.php.
The form already uses role="search" and contains a single svg + input,
so the semantic selectors are unambiguous.
templates/admin/head.php:
- admin-nav__logo now href="/" with target="_blank" rel="noopener noreferrer"
- Left arrow prefix (← via ←, aria-hidden) signals leaving admin
- sr-only suffix "(site public, nouvel onglet)" for screen readers
public/admin/login.php:
- Same treatment on the standalone login nav (was a bare <span>)
public/assets/css/admin.css:
- admin-nav__list: flex:1 removed; margin-left:auto added
→ entire link list now right-justified inside the nav bar,
mirroring the layout of the public site header
- .admin-nav__logout { margin-left:auto } removed (no longer needed;
logout is just the last item in a right-aligned list)
