Pull Request Overview

This PR successfully implements the 'deepin_small' ASCII logo; however, it does not currently comply with the project's contribution guidelines.

Specifically, the PR description is empty, and the mandatory 'Related issue' link (Closes #) is missing. The project guidelines explicitly state that new logos must be linked to an existing issue for acceptance. Furthermore, no screenshots were provided to verify the visual rendering of the 3-line ASCII art.

While the code implementation is straightforward, these administrative gaps must be addressed before merging.

About this PR

• Populate the 'Related issue' field (e.g., Closes #XX). Project guidelines require new logos to be linked to an existing issue.
• Please provide a PR description summarizing the changes and including screenshots of the rendered ASCII logo.

Test suggestions

• Validate that the 'Deepin_small' name correctly maps to the ASCII data in the logo selection logic.
• Verify the visual rendering of the 3-line ASCII art in the terminal.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Validate that the 'Deepin_small' name correctly maps to the ASCII data in the logo selection logic.
2. Verify the visual rendering of the 3-line ASCII art in the terminal.
