PART ICONS FOR THE TABLET SHOP

How it works:
- If a texture exists for a part, the tablet uses that image.
- If no texture exists, the tablet falls back to the drawn icon.

Recommended format:
- DDS
- Square image
- 128x128 or 256x256

Folder rules:
- Put custom icons in this folder.
- File name must match the part id.

Examples:
- turbo.dds
- spark_plug.dds
- engine_oil.dds
- gearbox.dds
- battery.dds
- seed_disc.dds
- cultivator_tine.dds

Category fallback:
- If a part-specific file is missing, the tablet also checks:
  - engine.dds
  - transmission.dds
  - hydraulic.dds
  - electrical.dds
  - cooling.dds
  - fluid.dds
  - implement.dds
  - default.dds

Notes:
- Images made by you are ideal.
- Internet images can also be used, but make sure you have the right to reuse them.
- Keep the background transparent if possible.
