+    The detect_nonweaer algorithm outputs non-wear values in 15-minute windows, where
+    each timestamp represents the beginning of the window. This structure does not align
+    well with the polars upsample function, which treats the last timestamp as the end
+    of the time series. As a result, using the upsample function would cut off the
+    final window. To avoid this, we manually map the non-wear data to the reference
+    measure's resolution.
