app didn't start
You're seeing this because the page loaded but its JavaScript never ran. The three usual causes:
dist/index.html
— not the project folder. The project's own index.html
points at /src/main.tsx, which only works while
running npm run dev. Run
npm run build first.
script-src 'unsafe-inline'. Check for a
.htaccess or security plugin adding CSP headers.
text/html, not text/plain or a download.
Open your browser's console (F12) — any error there will name the real cause.
