/* ============================================================
   FEDEARROZ — hoja de estilos única
   ============================================================

   Todo el CSS del sistema está aquí. Antes eran dos archivos
   (estilos.css y tema.css); se juntaron para que no haya que
   adivinar cuál manda sobre cuál.

   Está en dos partes, y ese orden importa:

     PARTE 1  Componentes. El detalle de cada pantalla: el
              inventario, la rejilla de códigos QR, las hojas de
              etiquetas para imprimir, el modal de la cámara…

     PARTE 2  El tema. Colores, barra, menú hamburguesa, paneles,
              tablas, botones y la portada. Va después a
              propósito: lo que se repita aquí gana.

   Para cambiar el aspecto de todo el sistema, toca las variables
   del apartado «COLORES Y MEDIDAS» de la PARTE 2.
