Changes in version 1.0.4 (2025-10-20)                  

  - Fixed an issue where the package would crash if the raster FVC had
    no values equal to 1.
  - The function now ensures that FVC values are properly handled to
    avoid computational errors.
  - FVC normalization is now silent: the function handles FVC values
    without issuing warnings.

This update improves the robustness of the package for cases where the
full range of FVC values is not present.
