This wasn't about picking a preset filter or dropping a style reference into a prompt. The visual identity — warm tones, ink-like linework, soft natural textures, that specific storybook-meets-architectural-illustration feel — was built intentionally, tested across different scene types, and refined until it held up whether the shot was a wide exterior or a close-up conversation. Getting AI to generate one beautiful frame is easy. Getting it to stay visually coherent across an entire narrative is the actual craft.
