Subjects
Best fit
- maps, interactive models, calendars, and portable tools
- third-party content that should wait for visitor intent
- embeds that need a useful no-JavaScript fallback
Avoid when
- ordinary linked content is sufficient
- the provider cannot be safely sandboxed
- the site lacks an approved provider and consent policy
Readiness

Limitations
- This is source-linked development evidence, not an exact clean release binding.
- The fixture uses local SVG media so automated proof does not contact a third party; provider-specific consent language, privacy review, CSP, performance, Safari, and independent owner acceptance remain site-level gates.
