/* ==========================================================================
   components/buttons.css - BOTONES. COMPONENTE. Fuente única: ningún módulo ni plantilla
   define tamaño, borde, radio, letra ni color de un botón (lo vigila core.tests.BotonesUnicosTests).

   Uso (siempre .btn + un tipo; tamaño opcional):
     <button class="btn btn-primary">Guardar</button>          principal (una por pantalla/ventana)
     <a class="btn btn-secondary" href="...">Volver</a>          secundario
     <button class="btn btn-danger">Eliminar</button>             peligro (borrar, anular, rechazar)
     <button class="btn btn-ghost">Limpiar</button>               solo texto (acciones menores)
     <a class="btn btn-soft btn-sm" href="...">Editar</a>         acción dentro de una fila
     <button class="btn-icon" aria-label="Cerrar">...</button>    solo icono, cuadrado
   Tamaños: normal 36px | .btn-sm 28px | .btn-xs 24px (tablas compactas).

   Nombres viejos que siguen funcionando mientras se limpian las plantillas (no usar en nuevas):
   .primary/.secondary (con .btn), .primary-action, .secondary-action, .secondary-button,
   .button-secondary, .btn-small (= .btn-sm), .row-action (= .btn .btn-soft .btn-sm).
   .icon-btn NO es un botón de icono: es la marca para quedar FUERA de este estilo (pestañas,
   chips, días de calendario que se pintan a su manera). El botón de solo icono es .btn-icon.

   El button:not(...) va dentro de :where() para que no aporte especificidad; así la regla queda
   en (0,1,1) y los tamaños/tipos de abajo ganan por orden.
