Space Dice — 6 versions until the math felt fair, here's the diff

Sharing the prompt history because I always wanted to see other people's + couldn't find any.

**v1**: "3 dice, sum closest to 21 wins" — model gave me a janky version where 22+ silently passed. Useless.

**v2**: Added "22+ is a bust, lose immediately." Better, but no tension — every run felt the same.

**v3**: "After the second die, show the player the running total and let them choose: roll the third or stop." Now there's a decision. But the model kept hiding the running total in tiny text.

**v4**: "Display the running total HUGE in the center after each die. The number should feel like the main character." Now it works.

**v5**: Added best-of-3 framing. Wrong call — slowed the loop down. Reverted.

**v6**: Tightened the score-submit pause to 600ms. Ship.

Lesson: the model is great at executing the next step, terrible at choosing *which* step is next. That's your job.
