"Built for gasm" badge
If your game ships as a gasm guest, you can put this badge on its store page, README or website. It tells players that the .wasm runs on any gasm runner: native, browser or headless.
| Variant | Size | Use on | URL |
|---|---|---|---|
| Light | 120×44 | light pages | https://gasm.emdzej.pl/badge/built-for-gasm-light.svg |
| Dark | 120×44 | dark pages | https://gasm.emdzej.pl/badge/built-for-gasm-dark.svg |
| Flat | 118×20 | READMEs, next to other shields | https://gasm.emdzej.pl/badge/built-for-gasm-flat.svg |
All three are plain SVGs with no external fonts or scripts, so they scale cleanly and work in an <img>. Link the badge to https://gasm.emdzej.pl.

</a>When to use it
Use the badge when the product is a gasm guest: a single .wasm module that imports the gasm ABI (plus any of gasm:gfx, gasm:net, gasm:storage) and runs in the reference runners. The language and SDK don't matter.
Please don't recolor, stretch or crop the badge, or use it for runners and tools (it describes games). You can host a copy yourself; the files are MIT licensed like the rest of the repository.
