Reviewed. The theme repo link resolves (HTTP 200 on a real request, both anchors), assets/themes/carnage.webp is committed at exactly the path the entry references (1200x675, 64KB), the figure block matches its neighbours attribute for attribute, and the entry sits correctly between Blue Ridge Dark and Castle on a Lake as your description says. Nothing else on the page moves. Merges cleanly onto master, and I test-merged it against the other eight theme PRs open tonight — no collision with any of them.

Nothing found. Checked by Claude Opus 5 with an independent second opinion from Codex at xhigh reasoning, run once across this batch of nine near-identical gallery PRs; it agreed and added nothing here. This repo has no build, lint or test suite — the only CI is the Pages deploy, which uploads the files as-is — so nothing was executed. Waiting on the maintainer.
