/* =====================================================================
   PROYECTOS ESPECIALIZADOS
   Hoja de estilos | Mobile first | Tema claro con bloques de color

   Sistema de color
   - Acción: teal (--brand). Botones, enlaces y foco. Siempre el mismo.
   - Espectro: coral, ámbar, violeta, cielo, lima y verde azulado. Cada servicio
     tiene su color (variable --c). Los tonos suaves y oscuros se derivan con
     color-mix(), así que solo hay que definir --c por componente.
   - Neutros: tinta verde oscuro (--ink) y grises verdosos.

   Formas: botones y chips en píldora, tarjetas 20px, contenedores grandes 28px,
   campos de formulario 12px.
   Tipografía: Geist (texto y títulos) + Geist Mono (etiquetas técnicas).
