/**
 * EHDS Presentation — Clean Editorial Theme
 *
 * Design principles:
 *   - Restrained color: teal as accent, not decoration
 *   - Flat design: borders over shadows, no glassmorphism
 *   - Typography-driven hierarchy: size + weight, not gradients
 *   - Proper centering: flexbox for block elements
 *   - Subtle motion: functional, not decorative
