- New hands-on/rules/ interactive page: five toggleable rule sources
(AGENTS.md, gate-discipline skill, Husky pre-commit, check-ui-contract
enforcer, commitlint) rebuild a ruled prompt live against a naive prompt.
- Visual system mirrors hands-on/starter (same palette, vanilla JS).
- index.html hands-on section now links both labs.
- docs/operations-guide.md gains a 'Hands-on rules lab' subsection.
- README project structure lists the new lab.
- verify.mjs passes content, interaction, and standalone checks for both labs.
