   Sistema de Bodegas Agrícolas — Hoja de estilos centralizada
   TODO el diseño vive acá — ninguna plantilla debe llevar style="" propio
   (excepción: imprimir_ticket.html, un documento de impresión aparte).

   Dirección de diseño
   --------------------
   Paleta: verde de campo cultivado + acento trigo/cosecha (dorado), sobre
   un fondo papel cálido — no el verde-Bootstrap plano ni un gris frío.
   Tipografía: Georgia (serif, con carácter) SOLO para el nombre del
   sistema y los títulos de tarjeta — el resto (formularios, tablas, texto
   de trabajo) usa la sans del sistema, que es la que mejor rinde en
   pantallas densas de datos. Los códigos de producto/maquinaria usan una
   mono — se leen como referencia, no como texto corrido.
   Firma visual: una marca de trigo dibujada a mano (SVG inline) en el
   encabezado, en vez de un emoji genérico.

   Organización: 1) Fuentes  2) Variables  3) Reset  4) Layout
   5) Header/Nav (con submenú "Inventario" y hamburguesa)
   6) Componentes  7) Utilidades  8) Responsive
