Embed `demo`

One script tag. No plugin, no build step, no framework — the widget draws itself into a shadow root, so the theme cannot reach in and it cannot leak out.

In the corner of every page

In WordPress: Appearance → Editor → Footer, add a Custom HTML block, paste this.

<script src="https://chat.italix.org/embed.js" data-bot="demo" defer></script>

Inside one section

Add a Custom HTML block where the chat should appear, containing an empty element and the tag. The panel stays open and takes the width it is given.

<div id="ix-chat"></div>
<script src="https://chat.italix.org/embed.js" data-bot="demo" data-mount="#ix-chat" defer></script>

Which sites may use it

https://www.italix.net
https://chat.italix.org

Exact matches only — scheme, host and port. https://example.org does not cover https://www.example.org, and that is deliberate: a suffix test would also match https://evilwww.italix.net. Adding one is a line in .env on this server.

What the page will do

fetch https://chat.italix.org/api/chat/demo/widget.json for the labels;
then post to /api/chat/demo/message, at most 20 times a minute per visitor;
keep the conversation id in the visitor's own localStorage, so a reload continues the same thread. Anyone holding that id can read that transcript — right for an anonymous documentation bot, and not for anything touching an account.

It is already running on this page

The corner button is this bot, loaded by exactly the snippet above — the same script, the same shadow root, the same cross-origin request path a WordPress page takes. A page that only *described* the embed would be describing something nobody had run.
