"""MetaMesh icon family v2 — one procedural mesh sphere + a badge per app.

  python3 meta_icons.py <out_dir> [APP ...]      # render icons (default: all)

Neutral icon = the sphere alone (MetaCore). Every other app = sphere + a dark
badge bottom-right: coloured ring (family colour), a white glyph, a label that
shrinks to fit. Spirit of v1, regenerated from code so nothing is ever lost again.
