   beehavioral.ai — single shared stylesheet.

   Pages identify themselves via a body class:
     <body class="home">            index.html
     <body class="sub stealth">     about.html, customers.html
     <body class="sub privacy">     privacy.html

   "sub" = dark themed sub-page chrome (default for sub-pages).
   "stealth" = giant centered display text (about/customers).
   "privacy" = scrollable policy content with header hierarchy.
