COSOM Lagoon SNES browser wrapper, November 2, 2026.
Copy the deployed snes/lagoon tree into public/snes/lagoon beside these source files.
Run node build.mjs (Node22+). It regenerates only the Lagoon pages, guide and wrapper.
Serve public/ over loopback HTTP; relative runtime/cartridge assets are required.
The complete supplied cartridge is retained as rom/lagoon-us.smc. The playable
rom/lagoon-us.sfc removes only its uniform64KiB01 tail. Cartridge hashes are recorded.
The runtime and its notices/sources are shipped separately in runtime/ and source/.
Personal saves, research fixtures and browser data are deliberately excluded.
Assists are off by default; manual checklist progress lives in browser storage.
