 Next:
 - Deploy the packaged operator, execute the live regional synchronization, verify persisted counts and temporal comparisons, then mark the regional time-series TODO complete only if PostGIS and browser evidence agree.

+Live source finding:
+- The regional Statbel synchronization imported all five requested snapshots successfully.
+- The first complete-region forest request was rejected by MercatorNet before download because the estimated 97.68 MB response exceeded its 78.12 MB service limit.
+- The operator now uses the 28 retained official municipality boundaries as resumable WCS partitions, merges them locally at the unchanged 10 m grid and applies the exact region-union clip before polygonization. It does not lower resolution or truncate the source.

 startup or map interaction. Partial statistical sectors remain area-weighted
 population estimates; forest hectares remain measurements in the harmonized
 10 m source representation and are not cadastral forest boundaries.
+The WCS source limits large responses, so regional forest retrieval is
