# Veola build.

# Requires the `templ` CLI (go install github.com/a-h/templ/cmd/templ@latest).
# The Tailwind standalone CLI is fetched on demand into bin/ (gitignored) — no
# node toolchain required. static/css/tailwind.css is a committed build
# artifact so a plain `go build` deploy still has styles; run `make css`
# (or `make build`) after touching templates or static/css/input.css.
