24-26: Consider updating the audit to reflect the current PR's additions.

The audit states that testing is completely absent and recommends adding Vitest + Husky/lint-staged, but this PR is actively implementing those exact recommendations. Consider updating these items to reflect their new status (e.g., marking them as "in progress" or "addressed") so the document stays accurate post-merge.

⚠️ Potential issue | 🟡 Minor

Missing path alias configuration — @/ imports will break in future tests.

The project uses @/ path aliases extensively (e.g., @/components/ui/badge, @/lib/data). Without mirroring these in the Vitest config, any test that imports a module using @/ paths (or imports a module that transitively does) will fail to resolve.

This works today only because utils.test.ts uses a relative import, but it will become a blocker the moment you add component or integration tests.

🔧 Proposed fix — add path alias resolution
 import { defineConfig } from 'vitest/config'
 import react from '@vitejs/plugin-react'
+import path from 'path'

 export default defineConfig({
   plugins: [react()],
+  resolve: {
+    alias: {
+      '@': path.resolve(__dirname, './src'),
+    },
+  },
   test: {
     environment: 'jsdom',
   },
 })

Alternatively, if a tsconfig.json with paths already exists, you can use vite-tsconfig-paths to keep it DRY.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
