nx_cross_genre.nx -- "cross genres WITH fidelity": reproduce a source (e.g. an anime frame) in a different genre (e.g. photoreal) while PRESERVING the content -- pose, identity, composition, action. The proof is a MEASUREMENT, content-neutral and genre-pair-agnostic (anime<->realism, photo<->painting, 2D<->3D), built on the classic CONTENT/STYLE decomposition (Gatys 2015): - CONTENT fidelity: structure/pose/identity preserved, STYLE-INVARIANT. Must stay HIGH. - STYLE match: does the output read as the TARGET genre? Must reach the target. - STYLE residual: does it still read as the SOURCE genre? Should be LOW (the genre crossed). A cross-genre reproduction SUCCEEDS iff content is preserved AND the target genre is reached. This is the scorecard that proves the system can carry a subject across genres at >= our current realism level, without quietly losing the subject. license_tier: ORIGINAL Refs: Gatys et al. neural style transfer (content loss vs style loss); domain-translation fidelity.
