Course cards go back to the colour-block art that previously sat under the captured frame, so the UI is unchanged apart from losing the photo. - Drop thumb.php, generateThumbnails(), captureThumbnail() and ensureThumbnailColumns(), plus the first-video tracking the scanner only kept to pick a frame source. - Drop the ffprobe fallback in probeDuration(); the pure-PHP mvhd parse is now the only scan-time probe, with the player's report on first play as the remaining fallback. - Drop THUMBNAILS_DIR/THUMBNAIL_SEEK_PERCENT from config, the thumbnail_* columns from schema.sql, the thumbnail counters from scan output, .thumb img from the stylesheet, and the matching README parts. Existing databases keep two now-unused folders.thumbnail_* columns; they are inert and can be dropped by hand if wanted. Claude-Session: https://claude.ai/code/session_014oyi9DMdhALrGz989MNNZJ
