/* ABZ "hero redesign" dark auth theme - shared by the student login gate
   (student_portal.html) and the educator login/signup page
   (login/integrated.html). Deliberately separate from hero_theme.css,
   which is the bright in-app theme used AFTER a student logs in - the
   pre-login/marketing-adjacent surfaces use this dark premium theme per
   the design system's own CLAUDE.md ("Background (near-black): #08060d").
   Ported from ABZ Student Login / ABZ Educator Login / ABZ Educator
   Signup .dc.html exports. */
