TICKER EMBED DEV
Three mount patterns. The drop-in script connects via the dev server SSE proxy ( /v1/demo/stream ).
1. Div-anchored mount
A <div data-ticker-feed> picked up by the embed script.
2. Script-sibling (Stripe pattern)
A <script data-ticker-feed> tag drops a ticker right after itself.
3. Standalone hosted page in an iframe (OBS browser-source preview)
This is what embed.trytickerapp.com/u/{handle}/{slug}.html renders. 38px tall, transparent background.
