/* Tutoria — shared component styles. Every colour is a token; each layout stylesheet
   (agora.css, noticeboard.css, studio.css) redefines the tokens and adds its own structure.
   Blue (--offer / --series-1) always means tutors & supply, orange (--request / --series-2)
   always means students & demand — validated for colour-vision deficiency on every surface. */
