Stellar Gauntlet

# Stellar Gauntlet 0.6.2

## 🪨 Cosmos blocks, redesigned as one family
Every block of the dimension is now cut from the same rock: one indigo tone, low contrast, soft clusters of shade and the same light direction. The islands finally look like one place.
- **Cosmic Stone**: the base rock, with two faint glints of starlight.
- **Cosmic Regolith** works like grass now:
  - star dust on top;
  - dust spilling over the rock on the sides;
  - bare rock underneath.
- **Cosmic Stone Bricks**: the same rock, cut and bevelled.
- **Cosmic Stellarite Ore**: the same stone, with cyan crystals set into it.
- **Cosmic Temples**: their corners now use Cosmic Stone instead of obsidian.

## 💎 3D Nebula Crystals
- A new 3D model of five prisms: a tall central one and four leaning outward.
- Violet bodies, darker at the base, with cyan tips that glow in the dark.
- They grow on any face (floor, ceiling and walls), and their hitbox matches the new shape.
- The previous art is kept as the inventory icon.
