lezer-lr.mjs imports esm.sh's /node/process.mjs, which the rewrite left as an absolute path: a 404 in the app, so every parsing language failed. It becomes ./node-process.mjs, copied from the server at the same ref, and an absolute import surviving the rewrite now fails the script. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
