| name: Deploy picomesh-yemu browser demo to GitHub Pages | |
| # Builds the full picomesh-yemu wasm demo and publishes it to GitHub Pages | |
| # under the repository's Pages site. The deployed page boots a riscv64 | |
| # Alpine VM in the visitor's browser via TinyEMU wasm, with the picomesh | |
| # mesh (gateway + 11 backends) launching inside that VM. No yetty | |
| # dependency — kernel + opensbi are built from this repo's 3rdparty | |
| # recipes, alpine minirootfs comes straight from dl-cdn.alpinelinux.org. | |
| # | |
| # Trigger: tag push `picomesh-<x.y.z>[-<pre>]`, plus manual dispatch. | |
| # 3rdparty (the linked C libs plus the riscv64 kernel + opensbi firmware) | |
| # is pulled as prebuilt release assets published by the build-3rdparty-* | |
| # workflows — so a run is ~3 minutes with no from-source 3rdparty build, | |
| # unless a release is missing for the pinned version (then it falls back | |
| # to building that recipe locally). | |
