/* Forma palettes. Light "Paper" is the default; dark palettes sit behind the sun/moon toggle and Settings → Appearance. The base accent is subject-neutral; subject accents (Settings → Appearance) tint each subject on top. --accent-2 is the partner colour for gradients. Study sheets keep their own fixed colours. Generated from palette-data.json by the scratch script; regenerate rather than hand-edit. */
