Tolerance For Variable Sketch Quality And Line Art Clarity

Unique: Explicitly documents and accepts variable input quality as a limitation rather than attempting to preprocess or enhance sketches automatically. This is a design choice that prioritizes simplicity (no preprocessing pipeline) over robustness, contrasting with tools like Photoshop that offer automatic contrast enhancement and cleanup before processing.

vs others: Simpler and faster than tools with preprocessing pipelines, but less forgiving of messy or low-quality inputs than professional software with built-in image enhancement.
