Desktop and mobile screenshots were visually reviewed. Healthcare, dining, and legal variants were rendered. PHP parsing and JavaScript syntax were checked.

## Limits

This is a controlled integration check, not a production-site audit or a full accessibility certification. The live website was not changed. Production theme/plugin combinations, real map loading, email delivery, and payment processing were not exercised. The new submission form requests review rather than taking payment.
