docs(screenshots): source fingerprint for #740 on the current dev — all frames pixel-identical

Validate on the conveyor's rebase eb439e81 failed preflight: the branch
changes visual sources (stairs), so the screenshot check is strict on it,
and the fingerprint was stale against the moved dev (#739, #742, #759).
The branch is rebased onto b84465e5 (inventory counts merged with #742:
lifecycle 89, total 204/200) and `docs:accept --identical` re-captured
all 11 frames: pixel-identical, only the source fingerprint moves.

Issue: #740
User-Visible: no
