Ship configuration

Nothing selected means no filter. Size and purpose narrow the hull list only — a part has no purpose, and its size is decided by the socket it goes in. DLC and design race narrow the hulls and every part dropdown; a part already fitted stays listed whatever is selected. Mark narrows the dropdowns only — a hull has no mark — and Best variants only is a lens rather than another choice: it replaces the mark chips instead of adding to them. The last row — Class, Ammunition, Heat, Damage bias, Mining, DPS limited by and Impact effect — narrows the gun and turret dropdowns only, those being the only parts the seven mean anything for.
