Firework Generator
Design firework rockets and stars with shapes, colours, fade, trail and twinkle, and get the /give or /summon command, with a preview of the burst.
Crafting gives 1 to 3; a command takes up to 255. It flies 20 to 31 ticks before it bursts (about 1.27 s).

How the game works it out
| Flight duration | 1 to 3 from gunpowder in the crafting grid; a command takes 0 to 255 |
| Stars | Up to 256 explosions on one rocket; each takes its own colours, fade colours, trail and twinkle |
| Trail and twinkle | A Diamond in the star recipe gives the trail, Glowstone Dust the twinkle |
| Damage | A rocket with stars hurts everything within 5 blocks: 5 plus 2 per star at the centre, less farther out |
| Summoned rockets | /summon needs LifeTime, or the rocket bursts at once; the generator writes the average flight |
| Checked in the game | Every shape and flight was placed in a chest, and a summoned rocket was read back |
