 *
 * v1 ships a single knob, `sphereDetail`, that scales the icosphere
 * subdivision used by every spherical mesh of a body (smooth surface,
 * liquid sphere, atmo shell, corona, core, effect layer). The full
 * surface stays untouched on `'standard'` — the default — so existing
 * callers see no change.
