/**
 * Generator (runs on Mac2, where git history exists): computes the exact cork PROD
 * tag-apply plan (Scope A + Scope B, same logic as apply-shopify-tags-PROD.mjs) and
 * injects it into scripts/_cork-apply-template.mjs at the __PLAN__ marker, emitting
 * a fully SELF-CONTAINED runner (scripts/apply-cork-tags-SELFCONTAINED.mjs).
 *
 * The emitted runner needs ONLY the 3 prod creds (env) + the `pg` package — no git,
 * no data/products.json, no reports/ — so it runs on Kamatera's /var/www copy
 * (which has no .git) with zero repo dependencies.
