fix: invert mouth curve (smile was rendering as frown); smoother blink

Browse Source 
Parabola sign was backwards — positive curve bowed the center up, an
upside-down U. Also: lid reveal now sweeps bottom-up like a rising lid,
blink runs in smaller steps, and the pupil redraw waits until the lid
has actually cleared it instead of flashing through mid-blink.
