/* AI FloLabs — hoja de estilos del sitio (v3 clara, 2026-10-04).

   Dirección: "papel y señal". Fondo papel cálido, tipografía editorial
   (Fraunces para titulares, Inter para cuerpo, JetBrains Mono para
   etiquetas técnicas), un acento "señal" verde azulado y un fondo vivo
   (canvas de nodos en flujo, ver main.js). La maqueta del documento se
   mantiene oscura como "captura de producto" con sus propios tokens.
   Sin dependencias ni build: CSS plano. */
