An interactive playground built with vanilla HTML/CSS/JS — drag-and-drop card layouts, SVG charts, 5 accent themes, an AI prompt studio, and a chat assistant. Every tweak auto-saves, and users can export/import their entire setup as a .js config file.
An interactive generator for any business — dealer, resto, toko, jasa — that reuses my client landing page styles (Vira, Kiki, Cinta, Singgih) as visual templates.
