/* ============================================================================
   nwif.css — NWIF Reporting design system (v4, 2026-09)
   A neutral, data-first reporting UI: cool grey canvas, white surfaces, one navy
   brand colour, Inter throughout, 1px borders instead of shadows, semantic badges.

   Scope discipline: every rule is class-namespaced (.nw-*) or targets Dash's own
   component classes inside .nw-scope. No bare element selectors, so the locked
   sponsor-report pages (inline styles, no classNames) render exactly as before.
