CI / php (push) Failing after 1m11s
- Rename $secret to $csrfSecret in public/index.php to make
intent clear at every call site; the value is the CSRF/turn-token
HMAC key, not just 'the secret'.
- Drop the stale 'Configure the router with the eight routes' comment
in public/index.php; the router now has sixteen routes.
- Drop the duplicate .bf-toast rule in public/assets/styles.css; the
second declaration (the new yellow box) is the active one, the
first (legacy green pill) is dead code from the editor era.
- Add a trailing newline to src/Views/home.php.
- Tighten the matchId regex in two tests from {16,} to {16} since
bin2hex(random_bytes(8)) always produces exactly 16 hex chars; the
spec's {16,} stays in production TurnToken.
No behavior changes; addresses the deferred-minors parked during
per-task review.
