- Replace Vike+React with SvelteKit for simpler SSR and routing - Update WASM build output paths from public/ to static/ - Add wasm-opt integration for WASM size optimization - Streamline tooling: remove ESLint, Prettier configs (use defaults) - Move build.rs to pacman-server/ (frontend no longer needs it)
