/* Eye-PIRLS shared stylesheet (landing, teacher, dashboard).

   The palette maps onto the MD3 token layer (md3.css, loaded first on
   every page): the warm scheme the owner picked for the learner page
   now themes the whole system. Semantic colors (green/red/amber) and
   the AOI/chart category colors keep their own values — they encode
   data, not brand. Fallbacks = the previous cool theme. */
