+"""Bilibili — multi-backend: bili-cli / OpenCLI / search API.
+
+yt-dlp was REMOVED from this channel (live-verified 2026-06): bilibili's
+risk control 412-blocks yt-dlp's requests in every configuration we
+tried — latest version, direct, proxied, with warmed cookies — while
+bili-cli keeps working (search/hot/video detail without login) and
+OpenCLI covers subtitles through the browser session. yt-dlp remains the
+YouTube backend; it just no longer serves bilibili.
