2. **The web port, as wasmga-me published it** — `source/stk-wasmgame-p2.diff`
   - SHA-256 `d727ada22bfeee6fe65bc9c843d8ccb5a34495dfc04128a3219a879d213ee286`
   - also at https://wasmga.me/engines/supertuxkart-1fb491f-p2/stk.diff
   - with its build scripts: `source/wasmgame-build.sh.txt`, `source/wasmgame-ports.sh.txt`,
     `source/wasmgame-pack.py`

3. **This build's changes to the game** — `source/stk-hotfix.patch`
   - SHA-256 `0e826456a656005fa8c5853b9b244eb7d95ff7c83b1347aad61efeb5e226f595`
   - `shared_gpu_objects.cpp` and `sp_base.cpp`: uniform buffers as large as their
     `std140` blocks, without which Firefox and Safari draw nothing.
   - `text_billboard_drawer.cpp`: text over karts draws in WebGL 2.

4. **The build** — `source/BUILD.md` has the toolchain, every library's exact version,
   and the commands.

The bundle page (`index.html`), `cassette.json` and `metadata.json` are part of this
build and are readable in the bundle itself. The only change from the page of the
previous build is that it loads the race music pack (`ensurePack("music")`).

The game data in the `.zip` packs is unchanged from the previous build. It comes from
the SuperTuxKart 1.5 release, shrunk and split by the scripts named above and
`android/generate_assets.sh` in the archive:
`SuperTuxKart-1.5-src.tar.gz`, 726,171,140 bytes, SHA-256
`33cf8841e4ff4082d80b9248014295bbbea61d14683e86dff100e3ab8f7b27cb`,
