####User story & summary:
As a mobile web user, I want a cleaner and less verbose account creation form so that I can view all required fields at a glance without scrolling, and complete registration with reduced information overload.
####Summary
Redesign the mobile web account creation form to follow Codex guidelines and reduce visual and cognitive complexity. The updated design shortens explanatory text, improves layout, and allows users to view all required fields on a typical mobile screen without scrolling.
