Checks that the page has exactly one main landmark

| | |
|---|---|
| **Rule ID** | `a11y/landmark-one-main` |
| **Category** | [Accessibility](/rules/a11y) |
| **Scope** | Per-page |
| **Severity** | warning |
| **Weight** | 5/10 |

## Solution

Each page should have exactly one `<main>` element or element with role='main'. This helps screen reader users quickly navigate to the primary content. Multiple main landmarks confuse navigation. Use `<aside>`, `<nav>`, or other landmarks for secondary content.
