Layout choices
| Layout | Containers | Use |
|---|---|---|
| Default | Ordinary Markdown | One message or a focused list |
two-column | :::left, :::right | Paired ideas or code/explanation |
three-column | Three :::col blocks | Comparable features or stages |
grid-2x2 | Four :::cell blocks | Four related categories |
split-left | Left content with background area | Text beside a visual |
split-right | Right content with background area | Visual beside text |
Use explicit fragment order across columns. Keep nested blocks simple enough for the parser and inspect the generated result; for complex cards or grouped diagrams use :::html plus :::css with the framework's layout classes.
