- Move embed_prod.go/embed_dev.go out of cmd/wotra/ into root-level
assets_prod.go / assets_dev.go (package assets). go:embed paths
must be relative to the source file; cmd/wotra/ cannot reach
../../web/build.
- Update cmd/wotra/main.go to import the root assets package.
- Change mise.toml build task from parallel depends to sequential
shell commands (build:web then build:go) so the frontend is always
compiled before the Go embed runs.
