/**
 * fleet.rstew.art — shell on Artificer tokens.
 * Visual DNA: navy #1c4e9e, orange #f37123, topographic ground (assets/topo.svg).
 * Artificer owns the polish pass after this shell.
 * Museo faces come from use.typekit.net/qfz2bgl.css.
 * That kit serves museo-slab and museo-sans at 300 and 700 only — not 400.
 * Body stays 300, display and labels stay 700, so a missing 400 does not drop the face to Georgia.
