Building the spec

The spec follows the DASH-IF authoring workflow and builds with Docker via the DASH-IF specs-builder image. Output goes to spec/dist/.

./build.sh              # HTML + PDF
./build.sh spec.html    # HTML only
./build.sh spec-serve   # rebuild on change and serve on http://localhost:8000
./build.sh help         # all targets

On Windows use build.bat with the same arguments.

Pull requests that touch spec/ build a dist artifact for review; pushes to main publish to GitHub Pages.
