Tune the Float embed's welcome teaser without touching code, plus a fix for image attachments in chat

The welcome teaser on Float embeds, the message bubble that greets visitors above the launcher, is now yours to shape without touching code. Turn it off, choose how long it waits before appearing, or mute its chime, either from the embed customizer on the Invite page or just by asking the AI assistant. Publish your changes and they reach embeds already live on your site automatically, so the greeting evolves with you instead of being frozen at install time. See the embedding guide for details.

Attaching an image could leave the assistant unable to reply: once a screenshot or photo entered the conversation, every following turn failed, both while building a Perspective Agent and in analysis sessions. Images now come through fine and the conversation carries on.
