Bounty: Dead Code Cleanup and Code Formatting (React)

[Ahmadkhattak1]

Summary

• Ran Prettier across the JavaScript/TypeScript codebase and cleaned up lint-reported dead code.
• Removed unused imports, props, locals, a duplicate Tailwind config key, an unused YouTube helper, and stale commented login code.
• Added narrow browser/API response types so ESLint is fully clean without suppressing rules.
• Kept behavior unchanged while reducing lint noise from unused code and explicit any usage.

How dead code was identified

• Ran ESLint and targeted @typescript-eslint/no-unused-vars findings.
• Searched for redundant helpers/imports with rg before removing them.
• Re-ran lint after cleanup to verify no dead-code errors remained.

Verification

• npm run lint (0 errors, 0 warnings)
• npm test -- --run
• npm run build

Verification remains green on this scoped cleanup: npm run lint, npm test -- --run, and npm run build all pass locally. Happy to adjust anything the maintainers want tightened before merge.
