/* =============================================================================
   ESD LAB - página projects (templates/projects.html): grid de
   tarjetas de proyecto, filtros activo/archivado, badges. Movido tal
   cual desde static/styles.css (A7.10), sin cambiar ningún valor ni
   selector. Confirmado con grep contra los 13 templates restantes que
   ninguna otra página usa su vocabulario, y que la sección no tenía
   ningún @keyframes propio embebido (verificado explícitamente tras
   el hallazgo de A7.9 con `login`).
