+Target is 100 clips per language. Locales covered by a single source get
+all 100 from that source; locales covered by two sources (de-DE, es-ES,
+fr-FR, ko-KR, nl-NL, pl-PL, pt-PT, ru-RU) get 50 from each so no single
+source dominates a shared locale.
 
 Clips are selected deterministically: each source split is sorted by its
-own sample id, then strided (`index = i * floor(n / 8)` for i in 0..7) so
-the 8 picks spread across speakers/sessions instead of clustering on the
-corpus's first few rows (which tend to share one speaker). No randomness
-is used. Unavailable/corrupt rows are skipped by advancing to the next
-candidate in sorted order, deterministically.
