/**
 * Inline-assertion smoke test for mentionPresets.
 *
 * The `@djangocfg/ui-tools` package has no test runner configured
 * (`package.json` only has build / clean / dev / playground / check).
 * Rather than introduce vitest just for this, we keep the assertions
 * inline and runnable as a one-shot Node script.
 *
 * Run:
 *   cd packages/ui-tools
 *   npx tsx src/tools/MarkdownEditor/mentionPresets.test.ts
 *
 * Or just trust `npm run check` (tsc --noEmit) to catch type drift —
 * the file is excluded from tsup's `entry`, so it never ships in `dist`.
