/* Design tokens for the AI Research Atlas.
   Light: "Paper & Ink" theme. Dark: "Night Desk" theme. Pairing: "The Lounge" (Fraunces + Instrument Sans).
   Theme and pairing by Susan Acharya · Designed using Design Lounge · https://www.designlounge.live (free to use, credit kept).
   Motion tokens: designlounge.live/motion. Chart hues: the dataviz skill's validated categorical palette,
   with the light set stepped darker so every hue clears 3:1 on the paper surface (validated with validate_palette.js). */
