Module icons 

SF Symbol → Material / emoji resolve for non-Apple hosts. SF Symbol → cross-platform icon resolve (Material ligature + emoji fallback).

Not SF Symbols outside Apple — similar glyphs only. Unknown names never fall back to a random first letter (that looked broken); use a neutral bullet.
