Level Grains
Shift individual grain regions so they all share a common baseline. Uses the selected reference statistic (mean, median, or minimum) per grain to compute the offset. Useful for consistent grain height comparisons. Equivalent to Gwyddion's level_grains.c module.

Notes
- Each connected region in the mask is treated as a separate grain.
- The target baseline is the average of all per-grain reference values.
- Use "minimum" reference when grains sit on different substrate heights and you want to align their bases.
- Combine with Grain Analysis to verify height distributions after leveling.
