The mix-up
You asked for a Page. The agent drew one. Then you said save it — and two different jobs got treated as one.
Making is free. Keeping a public URL is the keyed step. The recipe is the JSON. The HTML is a snapshot of that recipe, frozen once.
1. Keep it on your machine (no key)
Say: make a Page and save it so I can open it.
The agent drafts a pagespec, then calls `render_page` with a file path.
You get: an `.html` file you can open in a browser.
Also keep: the pagespec JSON next to it. That file is the Page. Without it you only have a frozen HTML snapshot — you cannot republish the same picture on purpose.
You do: bookmark or share the URL. Later, call `my_pages` to find it again (News #9).
Free key: up to 5 alive, 7-day TTL, watermark. Paid: more slots, it stays. Unguessable is not private — anyone with the link sees the Page and the twin.
