## Overview

This is a browser-based YouTube thumbnail creator. The main workflow is to upload an image, edit it with templates and interactive text/image controls, preview the composition in a YouTube-like layout, and export a PNG. The sampled editor source shows image loading, template application, Konva-based editing, and download behavior; the layout preview and authentication are README-documented capabilities whose wiring is not shown in the excerpts. The README names Clerk, but the sampled dependency manifest does not include it, so that integration remains uncertain.

Main entry points: [`components/thumbnail-generator.tsx`](https://github.com/vydyas/youtube-thumbnail-creator/blob/main/components/thumbnail-generator.tsx) (Editor state and actions), [`app/page.tsx`](https://github.com/vydyas/youtube-thumbnail-creator/blob/main/app/page.tsx) (Thumbnail creator), [`components`](https://github.com/vydyas/youtube-thumbnail-creator/tree/main/components) (YouTube layout preview)
