{"params":{"colorway":{"type":"choice","default":"stony-grey","label":"Colorway","describe":"Curated kit-coherent schemes for the same rock, each holding the same light-to-dark ladder of ejecta apron, crater floor, body and crater wall. stony-grey is the shipped grey-brown regolith shared with the kit's medium and large asteroids; iron-rust is an oxidised metallic body whose pits read as dark red oxide; carbon-dark is a near-black carbonaceous chondrite with cold pale ejecta; ice-pale is a bright icy chip whose pits fall away into cold dark shadow.","options":["stony-grey","iron-rust","carbon-dark","ice-pale"]},"rock":{"type":"color","default":"#9b8779","label":"Rock","describe":"Albedo of the whole asteroid mass \u2014 the one regolith colour on every facet that is not a crater apron or crater interior, and about two thirds of the triangles. This is the colour the object reads as from any distance."},"rim":{"type":"color","default":"#a59b91","label":"Ejecta apron","describe":"Albedo of the sloped apron ringing each crater \u2014 stone thrown out by the impact, the LIGHTEST zone on the model, one full value step above the body. This ring is what makes a pit read as a crater at thumbnail size; take it below the body colour and the craters go mute."},"floor":{"type":"color","default":"#85736b","label":"Crater floor","describe":"Albedo of the flat excavated floor at the bottom of each crater \u2014 settled rock a step below the body but a wide step ABOVE the crater wall. That gap is deliberate: a floor painted as dark as its wall fuses with it into one black hexagon and the pit stops reading as a bowl at every angle but straight down."},"wall":{"type":"color","default":"#54555e","label":"Crater wall","describe":"Albedo of the steep inner wall band between the raised lip and the floor \u2014 the darkest zone on the model and the \"darker crevice\" tone of the brief. It is the only dark rung, so it must stay a wide step below both the body and the floor or the bowl flattens into a painted disc."},"facets":{"type":"range","default":4,"label":"Facet density","describe":"Geodesic frequency of the shell, which REBUILDS the whole surface rather than smoothing it, so the triangle count moves with it. 3 is a brutally chunky chip of about 180 big planes, roughly 0.7 m across flats; 4 is the shipped rock at about 320 planes near 0.45 m; 5 is a finer 500-plane body near 0.35 m that reads more distant and more rounded. Crater mouths are re-sized against the facet grid rather than left as a fixed share of it, so every pit keeps a readable apron, wall and floor at all three values instead of shrinking into a flat dark mark at the fine end.","affects":"geometry","min":3,"max":5,"step":1},"craters":{"type":"range","default":6,"label":"Craters","describe":"How many impact craters are cut into the shell, taken in order from a fixed graded table so the first 6 are exactly the shipped ones and each added pit lands on a side that had none. 3 leaves a mostly pristine chip carrying only the big hero pit and the two raised collars that notch the outline; 6 is the shipped rock, cratered on all six canonical views including the top pole and the underside; 7 adds a small fresh pit whose apron crowds the hero crater, so a young impact sits against an old one.
