## 🐛 Bug Fixes

### Grid Resampling Stability

Fixed a critical crash that occurred when computing grid metrics with an input grid mask.

**What was affected:**
- The `grid_resampling.py` module could raise an `UnboundLocalError` when processing grids with invalid metrics.
- This issue was particularly problematic in scenarios where grid metrics could not be computed on a tile due to a fully invalid grid mask, leading to unexpected crashes.

**Impact:** Users working with grid masks that are fully invalid in the working area can now process their resampling without encountering crashes.
