   insights-hotlist.css — Insights · Rayon/Regio dashboard (Hot-list)
   Ported from the Claude Design handoff (2026-06-19-rayon-dashboard).
   Global stylesheet (linked from Web/App.razor) because the hot-list
   spans several components (page, filter bar, widget, sparkline,
   skeleton) with cross-component selectors (e.g. .hot-list__row--top
   .sparkline) that scoped CSS can't express without ::deep.

   Tokens only — every value references css/tokens.css. The .btn /
   .btn--primary primitive comes from css/components.css; the shimmer
   .skeleton base + keyframe is shared with insights-panel.css.

   Class map (semantic, mechanical to port):
     .hot-list-page            → Pages/RayonRegioDashboard.razor
     .hot-list-filter-bar      → HotList/HotListFilterBar.razor
     .pest-toggle / .pest-chip → └ pest-type multi-select
     .hot-list                 → HotList/HotListWidget.razor
     .hot-list__period         → └ 7/14/30-dagen segmented control
     .hot-list__row            → └ ranked location row (a link)
     .hot-list__delta          → └ signed delta badge
