nx_sudoku_wasm.nx

nx_sudoku_wasm.nx -- SOVEREIGN SUDOKU as a browser game: pure-Nishi, NO-FLOAT, BASE-RELATIVE. The same source is the native binary (base = an mmap'd buffer, provable by a gate) and the WebAssembly module (base = 0). Exports the estate's established game interface -- init / tick / render / score / ww / hh / fb_off -- so the SAME blit-only HTML packager that serves nx_wasm_2048 and nx_wasm_craft serves this, and THE PAGE HOLDS NO GAME LOGIC: it copies a framebuffer and forwards keys. WHY THIS REPLACES THE JAVASCRIPT. The /games sudoku previously ran hand-written JS: a second implementation of a ruleset we already had in NishiLang, untestable by any estate gate, and not sovereign in any sense. Rules, solver, generator, renderer and input now live in one NishiLang module that a gate can drive natively. There is no bank file, no data format, no host cooperation and nothing to keep in sync -- the module GENERATES its own proven-unique puzzles in-image. UNIQUENESS IS COUNTED, NOT ASSUMED, and it is not counted here: the one solver/counter/carver lives in nx_sudoku_core.nx and is shared with nx_sudoku (the bank tool). Composing it rather than copying it is the point -- two implementations of one ruleset is the duplicate-ruler defect. Clue floor 17: McGuire, Tugemann & Civario (2012) proved no 16-clue sudoku has a unique solution. license_tier: ORIGINAL No hw writes (Rule 26).
