/* PracticePilot — Advanced Performance Analytics + Exam Readiness
   Intelligence 2.0 (Phase 10), mounted into the EXISTING
   [practicepilot_dashboard] page as a separate, self-contained section
   below the Preparation Dashboard module. Strongly scoped under
   .ppilot-perf-*; reuses the SAME --ppilot-* color tokens as
   preparation-dashboard.css/student-dashboard.css — no new color system
   invented. Mobile-first discipline, identical to preparation-dashboard.css:
   no fixed widths beyond the host container, cards/tables stack to a
   single column before anything can overflow horizontally, tables scroll
   WITHIN their own card (never the page). */
