+"""
+Pre-generate each opted-in user's DAILY audio lesson so it's waiting for them
+when they open the app — no spinner, just press play.
+
+A user "opts in" by configuring a daily lesson in the app, which stores a
+per-language preference:
+    daily_audio_lesson_type_<lang>        three_words_lesson | topic | situation
+    daily_audio_lesson_suggestion_<lang>  the verbatim subject they typed (topic/situation)
+
+For each recently-active user that has a daily lesson configured for their
+currently-learned language and no lesson yet for their local "today", we run
+the same generation pipeline the on-demand endpoint uses
+(DailyLessonGenerator.prepare_lesson_generation + generate_daily_lesson),
+synchronously. Re-running is safe: users who already have today's lesson are
+skipped.
+
+The frontend still generates on demand (first day / cron miss / odd timezone),
+so this job is a pure latency optimization, not a correctness requirement.
+
+Usage:
+    python generate_daily_audio_lessons.py [--send-email] [--dry-run] [--days N] [--user-id ID]
