1// nx_photoreal_critic_sota_fetch.nx -- DEEP SOTA for the PHOTOREAL CRITIC (operator 2026-07-04: "you need a
2// HARD critic ... nishi researcher"; and the fresh lesson: real research = arXiv PAPERS + GitHub CODE +
3// papers-with-code LEADERBOARD, NOT wikipedia). Banks the actual image-quality-assessment / perceptual-metric
4// literature that a hard photoreal critic is built on: LPIPS + FID (perceptual/distributional), the IQA metric
5// catalogs (BRISQUE/NIQE/MUSIQ/MANIQA/CLIP-IQA = no-reference natural-scene-statistics), DISTS, and the PWC
6// leaderboards. Same sovereign stack as nx_voicegen_sota_fetch: own TLS-1.3, Mozilla CA, idempotent have-skip.
