Sumi Dark Ink Story Engine

Create 10-second hand-painted sumi-e ink story videos in the Sumi Dark style. A locked ink-wash style system - black, white and grey ink on warm paper - where ONE deep-red element carries the story through a three-beat micro-arc: establish, tension, revelation, all in a single continuous shot. Includes the full prompt template, a fully worked example, the three-beat story method, and a shot-chaining guide for building 30-60 second story films. Built for Gemini Omni Flash 1.1, vertical 9:16.
