Skipped heading levels (WCAG 1.3.1)
Jumping from h1 to h3 breaks the outline screen-reader users navigate. How Curbcut flags skips.
What fails
When heading levels increase by more than one step (e.g. h1 → h3), Curbcut records a moderate finding with the observed sequence.
How to think about it
Use headings for structure, not visual size. Style with CSS; keep the outline sequential.
