* BLOCK O2 — Every system state polished.
*
* Covers the four polished surfaces:
* 1. Error pages (404 / 500 / 403)
* 2. Empty state component
* 3. Skeleton component
* 4. Form validation script
*
* No mock pollution — each test renders the real component to JSX
* string output (or hits the real Hono router) and asserts on the
* rendered HTML.
