New scripts/sync/verify-screenshots.mjs asserts that every screenshot
referenced in a guide page is (a) a CAPTURE_TARGET in routes.mjs and (b)
indexed in registry.json with a non-empty depends_on. It exits non-zero
otherwise, so a doc image added without a capture target fails loudly instead
of silently going stale. Wired into `npm run sync:check`, which the /sync-docs
skill runs every sync.
Currently: 112 referenced screenshots, all tracked and indexed.
