  NeuraAI — practice layer
  ---------------------------------------------------------------
  Loaded only by the NeuraAI practice pages, on top of neura.css.
  The blog still uses the older template styles under /ai/assets.

  Signal contrast, measured on the group surfaces:

      --d-ai         #ff8a2a   dark ink on this fill is the button
      --d-ai-bright  #ffb04a   safe for text on the near-black canvas
      #ffffff on --d-ai        fails contrast, so never use white on the orange
      #04101f on --d-ai        passes — filled chips and primary buttons

  So the orange draws rules, dots and fills. Anything read in orange
  uses --accent-bright. A filled orange chip carries near-black ink.
