   RunbookAI — assets/css/style.css
   Bootstrap 5.3 customisation + app-specific components.

   CSS custom properties inherit the primary colour injected
   inline by header.php from branding.primary_color setting:
     :root { --rbai-primary: #4F46E5; }

   All local assets use root-relative paths (/assets/...)
   NOT SITE_URL — prevents CSS loading failures on subpages.
