The tab icon is ours

The icon Seascape showed in your browser tab belonged to the tool this product was originally built on. It is now the Seascape anchor, the same mark as the installed app and the logo on your emails.

Every tab, bookmark and pinned shortcut — seascape.bz now shows the Seascape anchor instead of a leftover heart from the old builder.
Nothing to do — the new icon appears on its own; a browser holding the old one in cache may need a hard refresh.
