/* =====================================================================
   CVP shell.css — the three chrome-free surfaces.

   1. FOCUS   the student sign-up / log-in / apply / pay flow. Nothing on
              screen but the logo, the step you are on, and the form.
   2. ADMIN   the staff dashboard. A sidebar and a work area, like a piece
              of software — not a page of the website.
   3. PORTAL  where a student studies. The same bones as ADMIN, dressed as
              a learning system: their courses in the sidebar, the lesson
              in the middle.

   This file is deliberately standalone: none of them load app.css, so
   no header, hero, news bar or WhatsApp button can leak in.
   Mobile-first, 360px baseline, logical properties throughout.
