Docs — hero cover reference and animated prism background showcase
The capstone of SPEC-101: document hero-cover and ship the animated prism background as a live, authored example. There is currently no docs example of media-position="cover" on hero at all.
The hero reference page gains a cover section: a plain image-cover hero (the one-attribute change from a normal hero), then the animated background — {% sandbox src="prism-scene" /%} in the hero's media zone under media-position="cover".
The mechanism note explains the contract stack: cover layout + SPEC-090 posture demotion (inert backdrop) + guest fill — and the motion/perf authoring contract (eager-only, dim-under-scrim, reduced-motion, capped DPR, boot-frame gradient).
The sandbox reference documents height="fill" in the attributes table and prose.
media-guests.md cross-links the pattern from the "Live program" section.
Pages render correctly in light + dark and at mobile widths; vite build green.
Dependencies
WORK-398 (hero cover host) · WORK-399 (guest fill) · WORK-401 (the prism scene). WORK-400 informs the eager-only guidance.
