/* =========================================================
   DERPLAC - landing (v6, paleta artesanal y cálida)
   Paleta:
   - Blanco #FFFFFF: fondo principal
   - Negro #000000: logo y textos sobre claro
   - Fondos oscuros en negro puro #000000 (el dueño no quiere el negro cálido/vino en fondos)
   - Óxido #9F5125 y vino #971732: secundarios, solo para texto, nunca de fondo.
     Hoy el óxido está solo en la palabra destacada de Trabajos. Botones y detalles en negro o blanco.
   - Excepción: el botón flotante de WhatsApp va en su verde #1FA855.
   - Vino #971732: reservado para algo especial, casi no se usa.
   Los grises de texto y líneas salen del negro cálido, no son colores nuevos.
   Esquinas: imágenes 10px. Botones, pestañas y chips en píldora.
   Tipografía: solo General Sans. Títulos bold en minúscula (primera letra mayúscula),
   textos en peso medio, etiquetas chicas en mayúsculas semibold con letras separadas.
   ========================================================= */
