+"""alib.ru book-marketplace search (3.2M listings, RU+KZ sellers).
+
+Usage: tools/alib.py "query"
+
+Site specifics (verified 2026-07-09):
+- Endpoint: https://www.alib.ru/find3.php4?tfind=<query>
+- Encoding: query must be **CP1251** percent-encoded (utf8 → mojibake "РќРѕР").
+- Pages are CP1251.
+- Search is STEM-BASED (word matches all inflections — unlike libgen) + phrase mode with
+  double quotes; also author-first, year-range, ISBN-digits, price-range fields.
+- Result rows: "<cat> || <Author> <Title> |Серия: ... <City> <Year> <Pages> <Binding>.
+  (Seller X, city.) Цена: N руб." — i.e. listings, not library records: good for
+  small-press / rare / out-of-print RU editions that shops don't carry.
