// Pipeline asset: extract-fig-images.sh → apply-asset-map.mjs → optimize-assets.sh
// 1. extract-fig-images.sh: estrae hash-named images da .fig → assets-src/
// 2. apply-asset-map.mjs:   copia da assets-src/ → destinazioni (src/assets/img, public/img)
// 3. optimize-assets.sh:    converte PNG fotografici → JPG q85, ridimensiona ≤1400px
