## Overview

This is a low-current-systems marketing site with an interactive estimate calculator. Visitors browse service and company information, select services and project details, calculate a preliminary estimate, then submit it for saving. The sampled code confirms local contact-form handling rather than a backend submission. The README is only the default Next.js starter guide; unsampled components are represented by their tree paths, but their behavior and internal wiring are not inferred.

Main entry points: [`app/page.tsx`](https://github.com/dmitriiutyrf/cryptoos/blob/main/app/page.tsx) (Home page), [`app/actions.ts`](https://github.com/dmitriiutyrf/cryptoos/blob/main/app/actions.ts) (Save estimate action), [`lib/db/index.ts`](https://github.com/dmitriiutyrf/cryptoos/blob/main/lib/db/index.ts) (Database client), [`app/components/EstimateCalculator.tsx`](https://github.com/dmitriiutyrf/cryptoos/blob/main/app/components/EstimateCalculator.tsx) (Estimate calculator)
