+/**
+ * Local ESLint plugin "conventions".
+ *
+ * Cross-cutting code conventions that the recommended rule sets don't enforce
+ * (and plain @typescript-eslint rules cannot express in one shot):
+ *
+ *   - interface-props: Svelte 5 props always go through a local `interface
+ *     Props` + `let { ... }: Props = $props()` (no inline generics, no inline
+ *     type imports, no untyped destructuring);
+ *   - no-string-union-alias: string-literal union aliases (`type Kind = 'a' |
+ *     'b'`) are banned in favor of a single `as const` object + indexed access,
+ *     so literal sets live in exactly one place.
+ *
+ * Rules are AST-only (no filesystem), see the tests in eslint-plugins/__tests__.
