Rules:
- Escape literal tags in text as \ or <tag>; never inside code or mention labels, which are already literal.
- Always fence code blocks; never indent them. One-copyable-block rule: make the opening and closing fence longer than the longest backtick run in the content. Triple-backtick content requires four-backtick outer fences; never use triple backticks both outside and inside.
- Hard line break = trailing \ replacing the space before it. Empty paragraph = .

Inline tags:
- , , , (the only underline); required when styled text has leading/trailing spaces.
- text; nest to combine: word.
- Use Label or for mentioning Notion entities user://..., HTTPS page URLs, collection://..., agent://.... Database mentions use type="database" to distinguish them from page mentions. Regular links use [text](url).

not -. Most accept color="gray|brown|orange|yellow|green|blue|purple|pink|red" (text) or _bg forms like "blue_bg" (background). Color a whole block or cell with its color attribute; use only for words inside text.

The title/label is body text right after the opening tag, never an attribute. Children follow a blank line — plain Markdown, no wrappers or > prefixes. Blank lines touching the opening or closing tags become stray whitespace; never pad.
