React Loan Estimator

Frontend onsite coding round to build a loan estimator UI with interaction, styling, calculations, and accessibility polish. Requirements Implement a React UI for a loan estimator. Complete user interactions, styling, and calculation logic. Add accessibility improvements. Be prepared to discuss debouncing and caching as follow-ups. Notes In one round, the HackerRank preview was broken, so the candidate had to write the UI without live visual feedback. Keep computation logic separated enough that it can be tested even if the preview is unavailable.
