/* ==========================================================================
   Brainy Brands — dark theme (homepage proof of concept)
   Reference: mcfconnect.com — near-black canvas, translucent glass panels
   (no blur, just alpha + hairline + light bleeding through). Adapted with
   Brainy Brands' own accent — a deep, confident blue rather than the
   reference's orange, so the palette reads as its own — and its bulb mark
   driving the ambient glow. Type matches the rest of the site: Archivo +
   Public Sans.
