| If you are encountering an error or not achieving your desired outcome, here are some potential reasons and recommendations to consider: | |
| 1. If you format only a portion of a word rather than the complete word, an error may occur. | |
| 2. The token map may not always accurately capture the region of the formatted tokens. If you're experiencing this problem, experiment with selecting more or fewer tokens to expand or reduce the area covered by the token maps. | |
| 3. If you use font color and get completely corrupted results, you may consider decrease the color weight lambda. | |
| 4. Consider using a different seed. | |
