Known interaction constraints
Some hardware diagnostics inherently depend on color vision, hearing, touch, motion, or a visual pattern. Text instructions, status controls, notes, and export features remain keyboard accessible, but an equivalent automated conclusion is not always possible.
Preferences
The interface respects reduced-motion and system color-scheme preferences. The theme control can switch between light, dark, and system modes.
Practical fallback
When a diagnostic depends on color, sound, touch, motion, or a permission that is unavailable, use the written procedure, local notes, and exported report to document the observed limitation.
