Review Comment:
✅ **CodeAnt verified this suggestion was addressed in subsequent commits and
marked this thread resolved** as of `6904e72`.
The loop now assigns formatted values with `df.iat[row_position,
column_position]`, addressing cells by physical position rather than
potentially duplicated row labels.
<sub>If that's not right, unresolve this thread and CodeAnt will leave it
open.</sub>
