   Bento de 4 bloques (Theme / Community / Tutoriales / Updates),
   cada uno con su propia demo interactiva. Referencia: Assets/parte 4.png
   Las cards se mantienen SIEMPRE oscuras (mismo criterio que sección 05),
   por eso usan tokens propios (--eco-*) que no cambian con el theme.
   Solo los dos azules de marca (--c-deep / --c-sky) como acento.
