/* =========================================================
   AI / AX Designer — section styles for the home page (AI mode)
   Builds on colors_and_type.css + kit.css. AX-specific only.
   The page wrapper carries .app--ai so --accent* = terracotta.
   Note: .ax-intro / .manifesto below are unused since the AX
   subpage was folded into index.html — kept for reference.
