 * Ajustes responsivos globais. O projeto é construído mobile-first em
 * style.css; este arquivo concentra apenas os breakpoints e ajustes que
 * não fazem sentido embutir diretamente no CSS de cada componente.
 *
 * Breakpoints adotados:
 *   - Mobile:    até 767px   (padrão, definido em style.css)
 *   - Tablet:    768px – 1023px
 *   - Desktop:   1024px – 1439px
 *   - Wide:      1440px+
