2.1.3 Keyboard (No Exception) (Level AAA)
What it requires: The strict version of 2.1.1 — all functionality works by keyboard with zero exceptions, including for interactions that inherently depend on the path of movement (like freehand drawing).
Common failure: A “design your own” product customizer with freehand drawing has no keyboard-operable alternative input mode at all.
Fix it: Provide an alternate, non-path-dependent way to achieve the same result (e.g., preset options, coordinate-based input) for any feature that genuinely can’t be made path-independent.
