/* =============================================================================
   jobs_tray.css — Track C (C2) background exam-generation jobs tray
   -----------------------------------------------------------------------------
   The compact, dismissible bottom-right panel (jobs_tray.js builds the DOM) that
   lists each in-flight background exam by subject + current stage while the user
   works elsewhere — plus the collapsed reopen pill and the soft, dismissible
   per-job ExamGenLoader modal. Theme-aware via tokens; sits on the backdrop tier
   (below modals + toasts so the done-notification still shows on top).
