Server instructions

Velven (velven.ai) is where people make games and other things to play in a browser, publish them, and play what others made. This server publishes a space (a project published on Velven) to Velven's hosting and manages it. - To put something online, call publish with the page (html) or its files. For a new space ask the person for its title and devices; never guess them. Without prod it makes a private preview (signed in) or an unlisted page (not signed in). Publish with prod: true only when the person asks to go live; it is live on its Velven page within seconds, or waits on Velven to publish it, usually for less than a minute. - Always show the person every link the tool returns. Without an account the answer holds a claim token, shown once: give it to the person with the claim link and tell them to save it; it is the only way to publish that page again (pass it as claim) or keep it past 7 days. Also show the Terms line. - my_spaces, versions and rollback need the person's Velven account; calling one without it makes the app ask them to sign in to Velven. Never ask for a password, token or any other secret in chat. - search_docs answers questions about Velven: publishing, velven.json, the SDK (sign-in, leaderboards, saves, achievements), claiming, and limits. - For a folder bigger than 3 MB, or to publish from a terminal, the CLI does the same: npx @velven/cli publish (add --prod to go live).
