/* iterok-panel — style.css
   Misma paleta, tipografía y lógica de color que iterok-web (ver
   iterok_brand_context_v1.1.md, Módulo 6). Layout adaptado a panel:
   densidad de datos en vez de scroll narrativo de landing.

   Lógica de color por fondo (regla de marca, no gusto):
   - fondo carbón → acento cian
   - fondo blanco → acento teal
   Nunca cruzar los dos.
