ThumbMaker
* This application creates a thumbnail maker using Hono for server-side routing and client-side JavaScript for image processing.
* It allows users to upload images, specify output options, and generate a composite thumbnail image.
* The app uses the HTML5 Canvas API for image manipulation and supports drag-and-drop functionality.
*
* The process is divided into two steps:
* 1. Generating thumbnails: Users choose thumbnail size options and create individual thumbnails.
* 2. Rendering: Users can create and export the final composite image with options for format and quality.
* This two-step process allows changing format or quality without re-rendering the entire canvas.
*
* Additional features:
* - Users can go back from the second step to the first one to regenerate thumbnails.
* - Dropping new files takes the user back to the first step.
* - A "Download Metadata" button is added to download a JSON file with thumbnail information.
