   GRUPO PIA · Blog (índice) · rediseño «humanizado» (2026-11)
   1:1 con `Blog.dc.html` del prototipo de Claude Design. Lo que allá era
   estado de React acá es una clase: `.off` (no se muestra) y `.on` (filtro
   elegido). Los `:hover` van con !important, como los generaba el runtime.

   El menú NO es idéntico al de la home, y así está en el prototipo: el punto
   de «Cotizá» late con `blogPulse`, la rayita del kicker usa `--accent`, y
   «Blog» va marcado fijo (sin indicador que se desliza).
