Steampunk GUI Resource Pack - Minecraft Java 1.21.1

This version fixes the previous black-border/quarter-screen issue.

Technical standard used:
- Every GUI texture is a 256x256 PNG, as vanilla expects.
- The actual visible GUI panel is placed at the top-left of the sheet.
- Unused sheet space is transparent, not black.
- Container panel sizes follow vanilla-style dimensions:
  - Most menus: 176x166 visible area
  - Large chest generic_54: 176x222 visible area
  - Hopper: 176x133 visible area

Install:
1. Put this ZIP in .minecraft/resourcepacks/
2. Enable it in Options > Resource Packs
3. Press F3+T after edits to reload textures
