Final answer:
For anticipated future edits to a logo design, it's best to keep the document with its layers intact, ensuring flexibility and ease of future changes.
Step-by-step explanation:
If you anticipate future changes to your logo design, the best practice would be to leave the document as a layered file for any future edits or changes. Flattening the image or merging layers is a permanent action that would prevent you from easily editing individual elements later on. By keeping the file with its layers intact, you ensure maximum flexibility for adjusting any aspect of the design, be it the typeface, color, or individual graphic elements.
