+// Maps ADIF DXCC entity numbers to ISO-3166 alpha-2 codes (flagcdn slugs),
+// so we can show the contacted entity's flag in the UI.
+//
+// Why not emoji flags? Windows does NOT render regional-indicator flag
+// emoji (it shows the two letters instead), and this is a Windows app — so
+// we use flagcdn.com PNGs keyed by ISO code instead.
+//
+// Numbers are taken verbatim from internal/dxcc/adif_numbers.go so they're
+// guaranteed correct. Coverage is the commonly-worked entities; an unknown
+// DXCC number simply yields no flag (graceful — better than a wrong one).
+//
+// French overseas territories (Corsica, Guadeloupe, Martinique, Réunion,
+// New Caledonia, French Polynesia…) are mapped to "fr": they fly the French
+// tricolore and several of their ISO codes aren't served by flagcdn.
