+//  China State Council statutory holidays for 2026. Calibrated to the
+//  公历日期 + 农历对应日 + typical 调休 pattern; **the official 国务院
+//  办公厅 announcement (usually released Nov of prior year)** is the
+//  ultimate source of truth. If a date here disagrees with 国务院
+//  notice when published, edit this file and re-release.
+//
+//  Reference dates used (公历 yyyy-MM-dd → 农历):
+//    2026-02-17 → 农历 正月 初一 (春节)
+//    2026-04-05 → 清明 (公历固定)
+//    2026-06-19 → 农历 五月 初五 (端午)
+//    2026-09-25 → 农历 八月 十五 (中秋)
+//
+//  In years where 中秋 falls within 6 days of 国庆, the State Council
+//  typically merges them into a single 8-10 day window. 2026 has
+//  中秋 09-25 (Fri) and 国庆 10-01 (Thu) → window 09-25 ~ 10-04 is the
+//  most likely pattern (with 10-10 Saturday or earlier 09-20 Sunday
+//  for makeup work day).
 //
 //  Data structure is a flat list rather than a JSON resource so the
-//  plugin bundle stays single-binary and dependency-free. To update:
-//  edit this file when the next year's official 国务院办公厅
-//  announcement publishes.
