/* Don Gastón — holding-company overview.
   Deliberately its OWN identity, distinct from every subsidiary brand it
   sits above (NWM navy/orange, Fracmo black/#FFD400, ClimAlerta's navy/
   orange "Tormenta") — a holding page shouldn't look like a reskin of one
   of the businesses it owns. Dark charcoal ground, a muted antique-brass
   accent (a "plaque on the door" register, warmer and less saturated than
   any subsidiary's accent), serif display for institutional weight paired
   with a plain grotesk for body/data. Single dark theme by design — this
   is a quiet, factual page, not a marketing funnel. */
