"""uptime-kuma — recipe-specific functional test (Phase 2 P3).

GETs `/` and asserts the served HTML carries uptime-kuma-specific markers:
- "uptime kuma" (or just "kuma") brand string somewhere in the page (title/body).
- A reference to one of the SPA's bundled assets (e.g., `/assets/`, `/icon.svg`, `kuma`).

Distinguishes "the SPA bundle is bound and being served" from "a generic 200 response with
some other content." Non-vacuous: an empty fallback page from a wedged uptime-kuma backend
would 200 but contain none of these markers.
