On /live-tv/ it sits in the player control bar next to Cast and Theater. On /live/ it's in the player toolbar and on every UP NEXT card. One tap: on phones your own share menu opens; on desktop this Previously sheet appears.
The link is a watchpreviously.com URL, not a twitch.tv URL. When it's pasted into a chat app, the card carries the Previously wordmark, red accent, the stream's artwork, a LIVE badge, and "Watch on Previously". This is the branding James asked for — on the share, not inside someone else's video.
Rendered per stream on our edge (cached ~5 minutes, so the LIVE badge never lies). Channel artwork — never a frame pulled from someone else's video. Shown here at full composition.
Tapping the shared link opens watchpreviously.com/live-tv/?c=court-tv: branded chrome, the stream playing, a "Shared with you" chip, the same Share button (the viral loop), and more live streams below. If the stream ended, an honest ended state appears instead — never a fake LIVE badge.
