+/** Shared ESLint base for the NestJS services (`auth-service`, `api-gateway`
+ * today). Legacy `.eslintrc` format, not flat config — matches
+ * `apps/web/.eslintrc.json`'s ESLint 8 era rather than introducing a second
+ * config format into the repo.
+ *
+ * Consuming package.json needs its own `eslint`, `@typescript-eslint/parser`,
+ * `@typescript-eslint/eslint-plugin` devDependencies — pnpm's non-hoisted
+ * node_modules means a shared config can't lend its own plugin resolution to
+ * a package that doesn't declare the plugin itself.
+ *
+ * Referenced from each service's `.eslintrc.json` as a relative file path
+ * (`"extends": "../../packages/config/eslint-preset/index.js"`), not as
+ * `"@duoc-thu/config/eslint-preset"` — tried that first, and ESLint 8's
+ * legacy shareable-config resolution only auto-resolves package names
+ * shaped like `eslint-config-*` / `@scope/eslint-config[-*]`, not an
+ * arbitrary subpath of an arbitrarily-named package. Confirmed live: the
+ * package-name form failed with "couldn't find the config", the relative
+ * path did not. */
