nx_vn_art.nx

nx_vn_art.nx -- the ecosystem GENERATES a VN background (the visuals gap, attacked honestly): a procedural dusk-storm lighthouse scene, integer-rastered (NO float) into a packed-RGB framebuffer, then written as a sovereign PNG (our own nx_png encoder). It is served as a same-origin static image (CSS background-image, NOT a JS blit, NOT a third-party fetch) on the live VN. Honest scope: PROCEDURAL atmosphere, not hand-painted CG -- a real step from styled-text to generated art, the first rung of VN visuals. license_tier: ORIGINAL expect_exit: 0
