One <script> tag. Zero dependencies. ~5 KB. Looks great on light & dark.
Pins the treat card to the bottom corner of every page. Set data-app so treats are attributed to this page.
Renders exactly where you place the tag — put it in your footer, sidebar, "support us" box, anywhere.
| data-app | Attribution slug recorded with every treat (shows in /stats). Defaults to the host page's hostname. |
| data-inline | Render inline where the tag sits instead of floating. |
| data-theme | auto (default, matches the host page's light/dark tone) · light · dark. |
The card is a self-contained dark surface (Shadow-DOM isolated — zero CSS bleed from your page). A supporter picks a bone tier and taps Give a treat; checkout runs one-tap via Stripe, attributed to ?app=<your-slug> so every payment is credited to the page that earned it. A custom "your call" amount opens the full page, where a larger treat earns a permanent do-follow backlink.
