+Spain CCTV Ingestor
+===================
+Sources:
+  - DGT (Dirección General de Tráfico) — national road cameras via DATEX2 XML
+    No API key required. Covers all national roads EXCEPT Basque Country and Catalonia.
+    ~500-800 cameras across Spanish motorways and A-roads.
+
+  - Madrid City Hall — urban traffic cameras via open data KML
+    No API key required. ~200 cameras across Madrid city centre.
+
+Both sources are published under Spain's open data framework (Ley 37/2007 and
+EU PSI Directive 2019/1024). Free reuse with attribution required — source is
+credited via source_agency field which surfaces in the Shadowbroker UI.
