   EduX shell — the design system shared by every page.

   Deliberately NOT in here: section layouts that only the homepage uses
   (.stp, .track, .why2, .close2, .feedbar, .thumb) and the .rv reveal
   classes. .rv sets opacity:0 and needs an IntersectionObserver to undo
   it — shipping it here would blank the content of every page that links
   this file without that script.

   Load it BEFORE a page's own <style> so the page still wins on its own
   components; this supplies identity, type, buttons, nav and footer.
