// Two cover blocks back-to-back so a single page exercises both branches of
// findOpaqueBackground's cover-handling path:
//
// 1. Image-only cover (dim-0, no overlay color) — the `__background` span has
//    `has-background-dim-0` → CSS opacity 0. The fix's fallback kicks in:
//    host gets `rgba(0, 0, 0, 0.5)`.
//
// 2. Cover with an opaque overlay span (dim-90, overlayColor: background) —
//    the span resolves to rgb(255,255,255) at opacity 0.9. The fix reads it
//    and emits host `rgba(255, 255, 255, 0.9)`.
//
// findOpaqueBackground doesn't look at the cover image, so a 1×1 transparent
// gif data URI is enough for the image-only cover to have its <img>.
