Suggestion: "Crystallization" mechanic — an analog of casting for creating solid modules

This mechanic allows players to create unique, indivisible blocks (crystals) through a casting process.

How it works:

1) The player designs a mold-module with a cavity (using cutting, extrusion, or assembly tools).

2) The mold is sent to a special building (e.g., "Foundry" or "Glassworks").

3) A resource (resin, molten glass, polymer) is poured into the mold, consuming materials.

4) The output is a finished crystal block — solid, non-voxel-divisible, with unique properties (strength, transparency, weight).

5) The block can be used in assemblies like a regular module but cannot be modified further with standard tools.

Benefits for the game:

1) Adds a new production cycle: from mold to finished product.

2) Expands creative possibilities — creating complex monolithic parts.

3) Introduces resource economy for casting.
