Clarity that doesn’t need to call attention to itself.
Ludic Sans keeps a generous x-height and open counters for dependable interface reading, then trades a little air for pace as optical size rises. The result is one voice that can sit quietly in a settings panel and still own a launch.
Weight, width, slant, and optical size remain independent. Use them to tune hierarchy rather than decorate it: denser for administration, calmer for long text, and tighter when a message has room to become an image.
