+/**
+ * fix_youtube_dest.mjs
+ *
+ * One-time fix: the backfill_uuid_filenames.mjs script failed to exclude
+ * YouTube items, which store dest as "yt:VIDEO_ID" rather than a real file.
+ * As a result, those dest values were replaced with random UUIDs, breaking
+ * embed URLs like youtube.com/embed/<uuid>.
+ *
+ * This script:
+ *   1. Finds all items with mime = 'video/youtube'
+ *   2. For each, re-extracts the video ID from the src column
+ *      (src holds the original YouTube watch URL: https://www.youtube.com/watch?v=VIDEO_ID)
+ *   3. Restores dest to "yt:VIDEO_ID"
+ *
+ * Usage:
+ *   node scripts/fix_youtube_dest.mjs           # live run
+ *   node scripts/fix_youtube_dest.mjs --dry-run  # preview only, no DB changes
