/* ==========================================================================
   dashboard-registration.css — Pass-3 admin section primitives.

   Page-scoped: linked from dashboard.html AFTER dashboard-panels.css so any
   selector specificity ties resolve in this file's favour where intended.
   Split out of dashboard-panels.css in Phase 3 sub-pass 3c step 1, when the
   parent file exceeded the ~1000-line tripwire from
   kore-architecture-folder-structure.md §5. Mechanical move only — no rule
   rewrites, no selector renames; visual result identical to pre-split.

   Sections (numbering matches the labels they carried in dashboard-panels.css):
     13. Dialog (idle-timeout prompt; base modal — grown by 3b's
         confirmModal() for danger ops)
     14. Phase-3 primitives — Registrations / Check-In / Summer Camp /
         generic data table / toast notifications
