Why Web Standards Are Missing a Left-Hand Option

As touch devices now account for over 50% of web traffic and approximately 10% of users are left-handed, the absence of a standardized handedness preference represents a significant accessibility gap affecting millions. Currently, apps like Procreate and SketchUp must individually implement mirror-image layouts, leading to duplicated effort and inconsistency. A standardized `prefers-handedness` OS-level setting would enable developers to detect user preference just like dark mode, making touch-first design truly inclusive.
