/* ============================================================
   Brand Assistant — floating chat widget
   Design: "bestie texting you back" — a night-plum panel, a hot
   coral/lime duo for accents, and a chunky rounded display face
   for the header so it reads like a person, not a support ticket.
   All colors are CSS variables — override them on .ba-root from
   your theme if you want to match your brand.
