- app.css: CSS quote chars in .clu-quote-text::before/::after were
literal smart quotes which broke as terminating string delimiters in
the tailwind v4 parser. Use unicode escapes \201E and \201C.
- tests/TestCase.php: force DB_CONNECTION=sqlite + :memory: in setUp.
phpunit.xml env section was being ignored by pest 3 runner, so
RefreshDatabase truncated the real MySQL between turns.
- .env.testing for clarity (sqlite memory).
