Accessibility

One owner per rule:

• Biome owns element semantics: image alt, keyboard support for custom controls, combobox ARIA, and label association.
• React Doctor owns structure and naming: dialogs, nested controls, accessible names, persistent labels, and described invalid fields.
• The local hook only pairs tablist with child tab roles and data-invalid with aria-invalid.

Do not duplicate checks. Escape hatch: // allow: a11y-skip [reason].
