scripts/fetch-drawio.mjs downloads the pinned draw.war into a cache (DRAWIO_WAR_CACHE, or DRAWIO_WAR for a local file), checks its SHA-256 and extracts the files named in drawio-files.txt plus a LICENSE with the Apache-2.0 text. scripts/check-drawio-files.mjs drives the embedded editor in headless Chromium from a full copy, records every requested file and checks or rewrites (--update) the list.
