The pipeline dispatches a full Validate for a `ci:golden` task, and
`screenshotsGateMode` read `full=true` as strict on any ref. Between betas
the source fingerprint on dev is legitimately stale (#479: re-captured for
the beta candidate), so every visual task failed preflight on the
conveyor's material until its author re-ran `docs:accept --identical` on
the current dev - #718 and #740 both did, and two visual tasks in a row
could not merge without it. On a task branch the mode is now `warn` even
with `full=true`; dev, main, PRs, the schedule and Release: candidates stay
strict.
