Category	Accessibility
Scope	Per-page
Severity	warning

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.
