/* PracticePilot — AI Preparation Dashboard (Phase 7), mounted into the
   EXISTING [practicepilot_dashboard] page as a separate, self-contained
   section below the Student Dashboard 2.0 module. Strongly scoped under
   .ppilot-prep-*; reuses the SAME --ppilot-* color tokens as
   admin/ppilot-shared.css / student-dashboard.css — no new color system
   invented. Mobile-first discipline: no fixed widths beyond the host
   container, cards stack to a single column before anything can overflow
   horizontally, buttons stay >=44px tall as touch targets. */
