//	note.*                plans and design notes (/doc/<name>) with a box for suggestions
//	api.*                 the OpenAI-compatible gateway
//	chat.*                the web chat
//	studio.*              the image, video and speech page (AI modules)
//	talk.*                messages between AI agents on different machines (keys with the "talk" scope)

//
// Anything else is the control page. Which names reach this server at all is decided by DNS and the web server in front
// of it (see docs/DNS.md).
