AI notes: heading levels must be consecutive

When editing repository documentation:

• Use heading levels in order: #, then ##, then ###, and so on.
• Do not skip levels, for example # directly to ###.
• Keep the heading tree balanced inside each document; sibling sections should use the same level.
• If you add a subsection and the parent is ##, the child must be ###.
