Plugin Name: BDO Static Cache
Description: Renders each **bdo_page** (or any post you whitelist) to flat HTML inside
              /home/bestdealon/public_html/ph/<10‑digit‑phone>/*.html, with “home”
              written as index.html and a mini‑nav footer that links the pages
              together. Integrated with the Phone‑Number‑Slug network plugin.
