Can I vibe code Plug in SEO?

Build a custom, private Shopify App to replace Plug in SEO functionality for a Shopify store using Next.js, Node.js, and the Shopify App Bridge / GraphQL Admin API.

1. DATA MODEL & SCHEMA:
- Create a database table `MetaTemplates` storing entity types (product, collection, page, article) and string rules for `titleTemplate` and `descriptionTemplate` using placeholders like {{title}}, {{vendor}}, {{price}}, {{store_name}}.
- Create an `AuditLogs` table to log sitemap crawl reports, broken URLs (404 status), and timestamped SEO issues.

2. CORE FUNCTIONALITY:
- Theme App Extension: Create an app block that renders a single standard Schema.org JSON-LD `<script type="application/ld+json">` block containing dynamic Product, Offer, AggregateRating, and BreadcrumbList objects.
- Bulk Meta Generator: Build a background worker that fetches products via Shopify GraphQL Admin API, evaluates the MetaTemplates against current product attributes, and mutates `seo.title` and `seo.description` fields if they do not match the template.
- Broken Link Scanner: Integrate the `linkinator` library. Write a cron route `/api/cron/scan-links` that downloads `https://[store-domain]/sitemap.xml`, recursively crawls internal links, identifies non-200 HTTP responses, and logs them in `AuditLogs`.
- Admin Dashboard: Build an App Bridge React interface allowing users to define template rules, click 'Run Bulk Update', view 404 error lists, and add 301 URL redirects via the Shopify `urlRedirectCreate` GraphQL mutation.

3. FAILURE MODES & EDGE CASES:
- If an product has no image or vendor, ensure template variables resolve cleanly to empty strings without leaving trailing separators.
- Throttle GraphQL mutation loops using bucket capacity headers to stay within Shopify API rate limits.
- Skip crawling external domain links during 404 link checks to avoid third-party blockages.

4. OUT OF SCOPE:
- Third-party social media integrations (OpenGraph tag management can be handled natively by standard Shopify themes).
- Billing integration or public app marketplace publishing setup.
