[bug\_fix] TS2307: Cannot find module '@/components/Button' or its corresponding type declarations.

Set 'baseUrl': '.' and 'paths': \{ '@/\*': \['src/\*'\] \} in tsconfig.json, ensure 'include' covers the src directory, and restart the TypeScript language server in the IDE.

Journey Context:
Developer scaffolded a Vite React project and immediately created a 'src/components' folder. They configured the '@' alias in vite.config.ts and began importing components using '@/components/Button'. VS Code underlined the import with 'Cannot find module'. They verified the file existed and the Vite dev server ran fine, realizing the bundler alias doesn't automatically teach the TypeScript compiler. They opened tsconfig.json and added 'baseUrl': '.' and 'paths': \{ '@/\*': \['./src/\*'\] \}. The error persisted until they noticed 'include': \['src'\] was missing the specific path pattern, and after adding it and executing 'TypeScript: Restart TS Server', the red squiggles vanished. The fix works because TypeScript's module resolution is independent of the bundler; the compiler needs explicit path mappings to resolve non-relative imports during type-checking.
