Single-frame HTML generator for cinematic chapter cards with authentic film aesthetics. You get 2.39:1 letterbox framing, warm orange light leaks (never cold blue), 35mm grain via SVG turbulence, and large serif typography in cream tones. Good for documentary openings, personal film projects, or video chapter breaks when you want that analog feel without After Effects. The template enforces classic film color theory (warm leaks only, max four hues) and includes optional film perforations and scratches. Ships as a single HTML file with motion respecting prefers-reduced-motion. Inspired by hyperframes' light leak work.
