/* ==========================================================================
   FILE 4: content-page.css — Informational Topic Pages, Code Cards & Contact
   ==========================================================================
   HOW THIS FILE WORKS:
   - Powers all 12 Informational Service/Topic Pages (service.php) and Contact (contact.php).
   - Also supports Topic-Specific Custom Overrides at the bottom using the
     `body[data-topic="slug"]` attribute on `<body>`, OR you can drop a custom
     stylesheet into `assets/css/topics/{slug}.css` (e.g. `generators.css`) and
     `header.php` will automatically load it for that specific page!
