Tab Order
Tab order is the sequence in which elements receive focus when Tab is pressed. It should match the visual content order (left to right, top to bottom). WCAG 2.4.3 (A). tabindex="0" adds to the natural order. tabindex="-1" allows programmatic focus. tabindex > 0 is an anti-pattern; avoid it.
