/* MVA Catalog — Modal & PDF-viewer styles
   ─────────────────────────────────────
   Loaded by index.html. Provides:
     • PDF viewer modal (used by components/pdf-viewer.js)
     • Compare-extractors modal (components/compare-modal.js, raw-extractor-modal.js)
     • Consensus tab navigation (admin/consensus.js)
     • Source-region listings + spinner used in the PDF panel

   The legacy admin UI (cards, kpi grid, badges, btn, chips, json-view,
   product-expand, mfg-health, etc.) was removed in the legacy-UI cleanup;
   its rules are no longer needed and have been deleted from this file.
