markup-assist

Deterministic gates for markup work. Each gate renders in headless Chromium, measures (DOM + pixel math, no VLM), and prints a kickback: a next-fix list with selector attribution. Your job is the loop: run → read kickback → fix the reported thing → re-run.

Prereqs: Node 24+, Playwright Chromium. If vlmkit is not installed: npm i -D @mizchi/vlmkit, then use npx vlmkit …. Sources are file paths or URLs. All commands support --json and most support --fail-on-suspect (non-zero exit) for scripting.
