One language file per faction (Zhestokost, Rossum & Douglas, Pirate) owns the shape kit, proportions, symmetry rule and
palette; the Zhestokost palette follows the lore page (ruling zhestokost-language-lore-text). The two probe hulls are
ported as fixtures. Checks: zones, emitter and radiator meshes, donor, body proportions, top-view mirror overlap,
length, triangle budget, muzzles nose-ward. Fixture-text tests need no OpenSCAD.
