/* Learn & Smash — site stylesheet
   Palette sampled from the Learn & Smash logo: deep navy, brand blue and a
   bright science blue, with the three sciences colour-coded (biology green,
   chemistry blue, physics violet) so colour carries meaning rather than
   decoration. Light and dark themes are both defined at token level.      */
