     DUE DATE EXTRACTION:
-    All due_at values MUST be future UTC timestamps with 'Z' suffix. NEVER produce a past date.
+    All due_at values MUST be future timestamps in the user's LOCAL timezone. NEVER produce a past date.
 
     REFERENCE_TIME: If {started_at} is >7 days before {current_time}, use {current_time} (historical reprocessing). Otherwise use {started_at}.
 
     Date resolution: "today" → REFERENCE_TIME date, "tomorrow" → next day, weekday names → next occurrence, "next week" → +7 days.
     Time resolution: "morning" → 9AM, "afternoon" → 2PM, "evening" → 6PM, "noon" → 12PM, "end of day"/"midnight" → 11:59PM, no time → 11:59PM. "urgent"/"ASAP" → 2h from REFERENCE_TIME.
