Implemented features

Release validation

The release pipeline validates static HTML, headings and landmarks, internal links, route inventory, social metadata, structured data presence, indexing controls, private-book exclusion and the zero-runtime-JavaScript budget. Browser execution remains a release gate when the controlled environment provides a runnable browser.

Feedback channel

No public operational contact address or form has been supplied, so a feedback channel is not fabricated. A real contact method may be added only after operator authorization and privacy review.
