-The review body must read at a glance: everything outside `<details>` blocks
-totals under 512 bytes. Only core information stays visible: the verdict, the
-summary line, and the section headings. Anything verbose goes into a `<details>`
-block whose `<summary>` is a few words, such as the title of an issue with the
-what, why, and how inside; the same for each strength, each recommendation, the
-reasoning, and any compliance notes. A finding you anchored belongs there only
-as its title, since its detail is on the line. Details blocks are top-level,
-never inside a list item, because Gitea breaks them there.
 
 For an `issue_comment` or `pull_request_review_comment` event, treat the `body`
 in the triggering comment payload below as the user's exact instruction.
