Some checks failed
Security / Security check (push) Failing after 1s
The approval card only rendered the payload section when a preview existed, so a step with no 'show:' showed nothing and the reviewer could not tell why. Now always show the section: a present payload scrolls inside a height-capped, copyable box; an absent one shows an explanatory hint (the flow's approval step chooses what to surface via its 'show:' field). Relabel 'data to be released' -> 'data to review' (the payload is review context, accurate to its source). Signed-off-by: flemming-it <stefan.a.flemming@googlemail.com>
