What this changes

POST /api/render compiled Markdown that the caller sends, using the site's own MDX pipeline (src/lib/renderMarkdown.ts -> next-mdx-remote). It accepted any string, with no login and no size limit.

The compile is CPU bound and runs inside the request, so the size of the request decides how long the server spends on it, and the answer is much larger than the document that was sent. Because the endpoint is open to anyone, one request with a large document is enough to keep the server busy for a long time and to make the other pages wait.

This pull request deletes the endpoint and the page that calls it:

• src/app/api/render/route.ts - deleted
• src/app/render/page.tsx - deleted

Nothing in the site uses them: no page, test, script or workflow links to /render, and the endpoint has no other caller. The two files are the whole of the feature that was added in e983e1c, so this is its exact inverse.

The Markdown the site does serve - task statements, solutions and assessment instructions - goes through src/lib/renderMarkdown.ts and is not touched.

Checks

• Type check, lint and unit tests pass.
• The production build succeeds and no longer lists /render.
• In the production build: POST /api/render and GET /render answer 404, and /, /tasks and /api/tasks answer 200.
