| Style | Format | Best For |
|---|---|---|
table | Markdown table with icons and descriptions | Formal documentation suites |
list | Bullet list with links | Lightweight nav headers |
Every target file must contain these markers (added automatically by md-scaffold.cjs):
<!-- nav:start -->
<!-- nav:end -->
The injector replaces only the content between sentinels, preserving all other content.
