   AI / DEVELOPER INSTRUCTIONS: STRICT OOCSS ARCHITECTURE
   =========================================================================
   Do NOT append new bespoke CSS classes to the bottom of this file. 
   1. Search for existing utility classes first (e.g., .btn, .btn--primary).
   2. Keep new classes modular, semantic, and reusable.
   3. Refrain from randomly tacking on styles for one-off elements unless absolutely necessary.
