og-preview asks YouTube, SoundCloud, Discogs, Reddit and archive.org their own way (oEmbed / public APIs) before the HTML scrape, so Discogs and Reddit links stop coming back 403 and every card gets a byline in siteName ("Discogs · Car Skid And Crash · 1986"), which both laklok sisters already draw. The vector client plays SoundCloud in place. lith's v2 function adapter read every Response with text(), turning og-image's proxied thumbnails into U+FFFD soup; non-text bodies now go through as base64. lith also runs the hourly metrics-daily rollup. tests/browser/laklok-link-previews.test.mjs proves the cards, thumbnails and player against fixtures (LAKLOK_CDP_URL for a remote Chrome).
