 * Build philosophy:
 *   - Tokens-first via CSS custom properties
 *   - BEM-strict class naming (.app-component__element--modifier)
 *   - Semantic HTML5 first (header/main/nav/table/section)
 *   - Zero dependency on legacy classes
 *   - Override esplicito di .wrap (WP admin) solo quando necessario
