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.

Full-eye repaints on every pupil step and blink frame flickered badly on
the 8-bit bus. Pupils now erase/redraw only themselves; lids paint
incrementally (BG rect closing, sclera chords opening). Mouth curve
deepened 20->32px and mood tiers raised so mood ~60 reads as an actual
smile instead of a 6px bend.
