Addresses an IndentationError at the definition of the
_blend_material_onto_frame helper function in
modules/processors/frame/face_swapper.py.
The fix ensures that the function definition line starts at
column 0 (no leading whitespace) and that the preceding
function's structure does not cause misinterpretation by the
Python parser. Duplicated/malformed definitions of related
helper functions were also confirmed to be removed in prior steps.
This resolves a syntax error that prevented your application from
starting.
