mesh is not a regular file

Error message

mesh is not a regular file: {mesh}

What it means

build() in blender_prop.py checks that the --mesh argument refers to an existing regular file before importing; the path is missing, a directory, or a special file.

Solutions

1. Check the mesh path for typos
2. Ensure the path is a regular file (not a directory or symlink to a missing target)

When it happens

Trigger: Thrown at skills/taste-application/scripts/blender_prop.py:159 when the library encounters an invalid state.
