/* Pawn to Professor v1.9.4a — Registration Scroll Fix
   ---------------------------------------------------
   The registration form became taller after Teacher/Learner + Terms/Privacy
   were added. On desktop the chalkboard is a fixed-height area and the board
   shell intentionally hides overflow, so the bottom of the form could be
   clipped and impossible to reach.

   Fix:
   - Desktop: keep the left "Request Access" branding stationary.
   - Make ONLY the registration card on the right independently scrollable.
   - Tablet/mobile keep their existing responsive page scrolling.
