AI — OpenAI (LaTeX & Mermaid)
Direct (my key)
Server proxy

Direct: key is stored in this browser and sent straight to OpenAI (works on any static host). Server proxy: the key stays on the server in api/config.php and the browser never sees it — requires PHP hosting. Powers the ✦ AI button in the diagram/equation dialogs.
