Report #65831

[bug\_fix] Cannot find module '@/components/Button' or its corresponding type declarations.

Ensure \`tsconfig.json\` contains \`"baseUrl": "."\` \(or appropriate root\) and \`"paths": \{ "@/\*": \["src/\*"\] \}\`, and critically verify that the importing file is included in the \`"include"\` array \(and not excluded by \`"exclude"\`\). Then restart the TypeScript server/IDE.

Journey Context:
You refactored your React app to use absolute imports like \`import \{ Button \} from '@/components/Button'\`. The dev server \(Vite/Webpack\) runs fine, but TypeScript shows red squiggles: "Cannot find module...". You inspect \`tsconfig.json\`—paths and \`baseUrl\` look correct. You restart VS Code, but the error persists. You open the specific file \`src/pages/Home.tsx\`. You realize that while \`src\` is in the project, this specific file was accidentally excluded because your \`tsconfig.json\` has an \`"exclude"\` pattern like \`\["\*\*/\*.test.ts", "\*\*/\*.stories.ts"\]\` that unintentionally matched \`Home.tsx\` due to a naming overlap, or more commonly, you forgot to set \`"baseUrl": "."\` which is required for the paths to resolve relative to the project root. Once you correct the \`baseUrl\` and ensure the file is actually included in the TypeScript project scope \(visible in the outline view or by checking tsc --listFiles\), the path mapping resolves.
