v1.0.3
UOverlayElement backdrop (0.2s ease) and UDrawer panel (0.55s easeOutExpo) had mismatched durations/easings causing a "boing" visual artifact on open/close. Unify both to 0.35s cubic-bezier(0.25, 1, 0.5, 1) easeOutQuart. Also fix exports map (src/* → dist/*) so consumers resolve built artifacts. Bump to 1.0.3.
