+/**
+ * One-shot rewrite of existing records into the shapes that reference
+ * `community.lexicon.*` defs:
+ *
+ *   dev.roe.usesItem  `links[].url` -> `links[].uri` (+ a role where the label
+ *                     says what the link is), `image` blob + sibling
+ *                     `aspectRatio` -> a single `community.lexicon.app.defs#image`
+ *                     carrying its own dimensions and alt text.
+ *   dev.roe.talk      `image` blob + sibling `aspectRatio` -> the same `#image`,
+ *                     tagged `#purposeLogo`.
+ *   dev.roe.location  flat `city`/`region`/`country`/`countryCode` ->
+ *                     `community.lexicon.location.address`.
+ *
+ * Every rewrite preserves the rkey and `createdAt`, and is skipped when the
+ * record is already in the new shape, so reruns are no-ops. Publish the updated
+ * lexicons (`pnpm lex:publish`) before running this.
+ *
+ * Usage:
+ *   node --env-file=.env scripts/migrate-records-to-community-lexicons.ts --dry-run
+ *   node --env-file=.env scripts/migrate-records-to-community-lexicons.ts
+ *   node --env-file=.env scripts/migrate-records-to-community-lexicons.ts --collection usesItem
+ *
+ * `--dry-run` reads over the unauthenticated client and validates the rewritten
+ * records locally, so it needs no credentials. Writing needs
+ * NUXT_ATPROTO_PASSWORD.
