Backup and undo

• Git commits are the rollback point; retain both source and report commits.
• To undo the isolated implementation, reset/revert the isolated branch to its pre-task commit under owner review; do not alter the canonical checkout.

Outstanding owner actions

• Independently review the two commits before integration.
• Configure and authorize any address autocomplete, MLS/provider, Zillow API, D1, or email credentials only in a future explicitly approved tranche.
• Keep AK deployment private behind Cloudflare Access; this task did not deploy.
