/* ============================================================
   TensorFlow Docs-inspired theme for MkDocs Material

   Material uses:
     --md-primary-fg-color  → header background color
     --md-primary-bg-color  → header text/icon color
   So for a white header we set fg=white, bg=dark text.
   Links/accents are controlled separately.
