/* Scoreo Learning — site stylesheet
   Layout concept: a student's binder. A deep-blue cover with colored subject tabs opens every page,
   sections are pages behind divider tabs, and the evidence is real homework in highlighter and red pen.
   Colors, type and tabs match the Scoreo Learning portal. */
