Walkthrough

The changes introduce a new color utility function groupToColor() that hashes group strings and maps them to a palette of colors with better contrast. The renderGroup() function now uses this new utility instead of the previous stringToColor() for determining default tag colors. Minor formatting adjustments are also present in model filter definitions.

Changes

Cohort / File(s)	Summary

Poem

🐰 A palette of hues, now grouped with care,
Colors distributed with hash-based flair,
No more drab tags in the rendering light—
The rabbit hops bright with contrasts so right! 🎨✨

在我这边出现了几个颜色相同的靠在一起，甚至不如之前的观感，还没有看是什么问题，暂时先revert了

maybe making it configurable is the best option...
