# Pipeline :
#   1. Installer Python 3.12
#   2. pip install multilingualprogramming[wasm]
#   3. python scripts/compile_wasm.py
#      → public/mandelbrot.wasm    (binaire WebAssembly)
#      → public/benchmark.json     (résultats de benchmark)
#      → public/mandelbrot_transpiled.py (Python généré)
#      → public/mandelbrot.ml      (copie du source français)
#   4. Déployer public/ vers GitHub Pages
