A dark-mode Twitter/X in-feed card for an active Twitter Space. The card has a soft purple gradient background (midnight purple to deep indigo) with a pulsating animated-style ring around a row of five circular speaker avatars. The Space title reads: "Is the VC model broken? Founders, investors, and skeptics". Below the title a listener count badge reads "4,821 listening" in white with a purple dot. The host avatar ("@capitalcritic", avatar: a minimalist magnifying glass in white) has a glowing ring and "HOST" label. Four co-host avatars in smaller circles. A large purple "Join" button sits bottom-right. The card is embedded in the standard dark tweet feed — adjacent tweet cards partially visible above and below, showing continuity. Black background outer frame, purple inner glow.
