SQLite performance (Database::__construct):
- PRAGMA journal_mode = WAL: eliminates full-DB read locks on write, safe
for concurrent PHP-FPM workers
- PRAGMA synchronous = NORMAL: durable on commit without full fsync per write
- PRAGMA cache_size = -8000: ~8 MB page cache per connection
Accessibility foundation (WCAG 2.1 AA):
- common.css: add .sr-only utility, .skip-link (hidden until focused),
global :focus-visible (2px purple outline, 2px offset),
prefers-reduced-motion guard; remove bare outline:none from
.site-search__input
- admin.css: same :focus-visible, skip-link, and motion guard scoped to
admin purple; remove outline:none from .admin-input/.admin-select/
.admin-textarea and .admin-filters select (both had :focus border rules
already, so focus is still visually communicated)
- search.css: remove outline:none from .search-filter-select (already has
:focus border-color rule)
- All 5 public pages (index, search, tfe, apropos, licence): add
<a href="#main-content" class="skip-link"> as first child of <body>;
add id="main-content" to <main>
- templates/admin/head.php: same skip link; aria-label="Navigation admin"
on <nav>; id="main-content" on all 10 admin <main> elements
All 4 test suites pass (unit, integration, security, rate-limit).
Implements the admin user management UI as a self-contained PHP password
change/set flow — no SSH or sudo required.
- public/admin/account.php: shows auth status (PHP hash present, credentials
file path), password change form (requires current password when one exists,
min 12 chars, confirm field), and a danger-zone form to delete the
credentials file entirely
- public/admin/actions/account.php: CSRF-guarded POST handler; verifies
current password via AdminAuth::login() before accepting a new one;
generates bcrypt (cost 12) hash; writes config/admin_credentials.php
atomically via a temp file + rename; regenerates session on success;
redirects to /admin/login.php when credentials are deleted
- templates/admin/head.php: 'Compte' nav link added (active on account.php)
- public/assets/admin.css: .admin-account-status, .admin-section-title,
.admin-field-hint, .admin-danger-zone component styles added
Note: the nginx htpasswd flow (manage-admin-users.sh) requires root on the
server and is intentionally kept as a CLI-only operation.
