Runner Summary

Checklist for Adding a Runner

• All frames are PNG files named <runner-name>-frame-<N>.png (numbered from 0), with a height of exactly 36px, a width between 10px and 100px, and all frames share the same size.
• The zip contains only the frames — no .DS_Store, __MACOSX/, or ._* entries.
• The runner is my original work, or I hold the rights to it, and I consent to its distribution under this repository's license (Apache-2.0).
• The runner does NOT contain third-party intellectual property (e.g., Pokémon, Mario, or other copyrighted/trademarked characters).
• Files are placed at runners/<runner-name>/ as <runner-name>-frames.zip, metadata.json, and preview.png.
• runners/manifest.json includes the new runner name and stays sorted alphabetically.
• metadata.json contains the correct author, displayName, type (monochrome or color), and tags.
• preview.png is an animated PNG (APNG), 36px tall, at most 100px wide, and animates correctly.
• I have read CONTRIBUTING.md and followed the steps described there.

None of the items on the checklist are checked. Please make sure to review each item one by one.

Also, looking at the runner preview, the colors change too quickly and it’s not easy on the eyes, so I cannot accept it as it is.
