outbound-only-exposure (corrected sealed-vault image) + secret-zero (the seed-
key circuit-tree, _R revision). Both verified against their prompts, optimized
to webp (17KB / ~120KB). Completes hero coverage for all 6 posts.
Add an optional hero field to the blog schema; render it on the post page and
as the index card thumbnail. Ship 4 verified Nano Banana hero images (shipping/
init-gating/authentik/workload) as optimized webp (64-134KB). Publish the
secret-zero post. (outbound hero pending — its file was a dup of shipping;
secret-zero hero pending generation.)
