/* ============================================================
   BRAIN-MIMETIX · hero + reference skin  (Tovexa Digital)
   Loads AFTER style.css, so everything here wins the cascade.

   Part 1 — SKIN: retunes the AURA tokens to the reference
   image: near-black neutral ground, warm ember bloom top-right,
   silver grotesque headline. The electric blue stays as the
   *neural* colour (cortex, markers, progress, chips) — in the
   reference the object is cool while the environment is warm,
   and this keeps that split. Flip --accent-rgb to the ember
   values if you ever want the whole console warm too.

   Part 2 — HERO: the split masthead layout (unchanged logic).
