/* products.css - Modular styles for the Products Section
   ------------------------------------------------------
   Purpose: Provide a standalone, themeable and responsive
   products/categories section for TopNet. This file is
   intentionally scoped and uses CSS variables from
   variables.css. Import this file from index.html.

   Notes:
   - Avoids global selectors to prevent collisions.
   - Uses CSS Grid for responsive layout and flexbox
     inside cards for equal-height content.
