review: PR #305 dark-crystal style human gate

[WalksWithASwagger]

Goal

Review PR #305 (feat: add dark-crystal signature style) and decide whether its needs-human gate can be cleared.

Current evidence

• PR: feat: add dark-crystal signature style (order + chaos poles) #305
• Branch: feat/dark-crystal-style
• State observed: non-draft, CLEAN, checks passing, still labeled needs-human.
• Public surface if merged: new style entries dark-crystal and dark-crystal-chaos.

Scope

Review only. Do not merge from this issue.

Check:

• Style registry entries and naming.
• styles/dark-crystal.md doc quality and public package boundary.
• Whether palette/brand terms are intentional and safe to publish in Rafiki.
• Whether tests in the PR body are sufficient or need rerun.

Acceptance criteria

• Produce a clear recommendation: merge-ready, needs changes, or keep human-gated.
• If merge-ready, list exact checks that passed and whether needs-human can be removed.
• If changes are needed, name the smallest patch.
• No generated local images or portal outputs are committed or exposed.

Tests / verification

• gh pr view 305 --repo WalksWithASwagger/rafiki --json statusCheckRollup,mergeStateStatus,isDraft,labels
• gh pr diff 305 --repo WalksWithASwagger/rafiki --name-only
• npm test
• python3 scripts/check-doc-links.py
• python3 scripts/check-public-boundary.py
• npm run smoke:dry-run
• npm run pack:check

Hard stops

• Do not merge PR feat: add dark-crystal signature style (order + chaos poles) #305 without explicit KK approval.
• Do not remove needs-human unless the review result explicitly justifies it and KK approves that action.
