/*
 * Custom CSS for Medok website with mobile optimisations.
 * This file is based on the original styles.css from the med_ok repository.
 * It includes several improvements for mobile devices:
 *   - Larger tappable area for the burger menu (44×44 px and centred bars).
 *   - Reduced hero section height and more flexible heading sizes on small screens.
 *   - Smaller gaps in the products grid and additional padding within cards on mobile.
 *   - Restored sticky CTA for mobile with a fixed bar at the bottom of the screen.
