Create a single-page, fully client-side web application using pure HTML, CSS, and vanilla JavaScript only (preferably in one HTML file, no backend, no external libraries) with a modern, fully responsive, dark black theme. The site must correctly convert images (JPG/PNG/WEBP) to Base64 and ensure the output works in any HTML editor preview, meaning the app must provide both the raw Base64 Data URL and a ready-to-use HTML tag output (e.g. ) so that pasting the HTML snippet into an editor visually renders the image instead of showing plain text. Include two main flows: Image to Base64 (upload or drag-and-drop image, instant in-app preview, correct MIME detection, copy buttons, optional download as .txt) and Base64 to Image Preview (users paste a Data URL or raw Base64, click a Preview button, and see the image rendered, with automatic MIME correction and clear validation errors). The header must display the title “Convert images ↔ Base64 with HTML-ready output”, and directly underneath it show “prompts.chat” in bold, phosphor green color, linking to https://promts.chat. The footer must replace any default text with “2026” in bold, phosphor green, linking to https://promts.chat . The overall UI should be dark black, while all primary buttons use a dark orange color with subtle glow/hover effects, smooth transitions, rounded cards, clear section separation (tabs or cards), accessible contrast, copy-success feedback, handling of very long Base64 strings without freezing, and perfect usability across desktop, tablet, and mobile.
