/* =====================================================================================================================
   MBPrep for every health course: this project's pieces, on top of the classic kit (/pub/assets/site.css).
   Every page loads, in order: layout.css, fonts/fonts.css, site.css, health.css. A fix here lands everywhere.

   Colours are the classic tokens only (--bg --surface --fg --muted --border --accent --accent-2) and soft tints mixed
   from them. A few panels keep the light palette in both themes, as the classic app does for "always ink or lime"
   panels: lime carries ink text, the indigo board half and the Galen slab stay deep. Those fixed values are the
   classic light tokens, named below so they are never retyped.

   BRIEF 3 (built after Brief 6): the course page template (course-physiotherapy.html, course-lab-science.html) and

   white cards), Brief 5/6 finish (two-tone heads, tinted tiles, glossy pills), very dark mode from the tokens.
   Lime marks school exams, indigo marks board exams.
