   New-design styles scoped under .tst so its generic class names (.section,
   .btn, .quotes…) can't collide with main.css or other pages' scoped sheets.
   Token block, primitives, and section conventions match educators.css /
   students.css (Inter + Source Serif 4, light/mist/dark sections). The global
   site header/footer (main.css) supply the chrome. */
