feat: super mode humans — shirtless, ridiculous muscles, gleaming teeth

Win rate >0.9 triggers super mode:
- Shirtless with full muscle anatomy (traps, pecs, 6-pack abs, v-lines)
- Massive bulging biceps with veins and separation lines
- Thick bull neck with sternocleidomastoid definition
- Round deltoid shoulder caps
- Quad and calf definition through pants
- Big gleaming white grin with tooth sparkle in all poses
- Championship belt instead of regular belt
- No glasses or beard (too cool for that)
