Field notes
The interface accepts a file, a dropped file, or pasted YAML, with a stated 25 MB ceiling. Its presentation distinguishes YAML from relaxed JSON by calling out documents, anchors, aliases, duplicate keys, and custom tags. Alias expansion is described as bounded for unusually complex inputs, and the page says file contents are processed locally, while ordinary page and asset requests still reach the hosting provider.
