Generates professional static HTML presentations with 36 themes, 15 full-deck templates, and 31 layouts, all driven by pure CSS and no build step. The standout feature is presenter mode: hit S and you get a popup with live previews of current and next slides, draggable speaker notes (150–300 words of 逐字稿 per slide), and a timer. Everything stays pixel-perfect in sync via iframes and postMessage. Use this when someone asks for slides, a pitch deck, or says they're giving a talk and need a script to stay on track. It handles English tech presentations and Chinese 小红书 posts equally well, with themes ranging from Tokyo Night to cyberpunk neon. Keyboard navigation is built in, and you can export to PNG via headless Chrome.
