Can I vibecode Iubenda?

Build me a self-hosted cookie consent banner and consent log to replace Iubenda's cookie solution. Requirements:

- Node.js 22 + TypeScript in one repo: `banner/` (one JavaScript file built with esbuild, no
  dependencies) and `server/` (Fastify). `npm start` serves the log API and an admin page on
  http://localhost:4880.
- Banner: on a first visit show Accept all, Reject all and Customise with the categories necessary,
  preferences, analytics and marketing; Reject looks as prominent as Accept. Store the choice in a
  first-party cookie for 180 days and ask again when `policyVersion` in config.json changes. A
  footer link reopens the dialog.
- Blocking: `<script type="text/plain" data-category="analytics" src="...">` runs only after consent
  for that category; iframes use `data-src` the same way. A MutationObserver holds back matching
  nodes that other scripts add later.
- Consent Mode: before any choice call `gtag('consent','default', ...)` with ad_storage,
  analytics_storage, ad_user_data and ad_personalization denied, and update it on every choice.
- Cookie list: `npm run scan` opens each URL of my sitemap.xml with Playwright, collects cookies and
  localStorage keys, and writes cookies.json (name, domain, lifetime, category set by hand) that the
  Customise view shows.
- Log: the banner POSTs policyVersion, chosen categories and a timestamp to /api/consents; the server
  adds a hash of IP plus user agent with a daily salt and stores rows in better-sqlite3 at
  ./data/consents.db. The admin page (one password in .env) lists, searches and exports CSV, and a
  nightly job deletes rows older than RETENTION_DAYS.
- One site per install. No accounts, no telemetry; the banner calls only your own server.
- Out of scope: generated privacy-policy text, IAB TCF, geo-targeting, A/B tests, mobile SDKs.
- README: how to tag scripts, that tags added by a tag manager must be tagged too, a warning that a
  banner is only part of compliance, and that the policy text should be read by a lawyer.

Opens your agent with the prompt filled in, you press enter. Or copy it and paste it into an empty folder.
