{"params":{"colorway":{"type":"choice","default":"galvanised-verdigris","label":"Colorway","describe":"curated kit-coherent scheme; sets all nine zones together and keeps the frame, the deck floor and the two accent notes apart in value so the run never collapses into one grey bar. galvanised-verdigris is the reference off the refs: pale zinc frame, near-black grating floor, mint-green finials and centre rail bay, warm orange bloom at the beam ends. oxide-run is a run mostly gone to oxide \u2014 warm brown-orange frame, dark red rust, near-black grating, deep teal accents. mint-paint is a catwalk somebody painted seafoam and the paint held, with the same orange bleeding through at the fixings. brass-works is a salvaged brass-and-cream run off a boiler house: pale brass frame, bronze legs, cream timber battens.","options":["galvanised-verdigris","oxide-run","mint-paint","brass-works"]},"iron":{"type":"color","default":"#b6bfc2","label":"Galvanised frame","describe":"albedo of the raw galvanised ironwork \u2014 both handrails, all eight posts and the filigree in the two outer bays. The largest zone and the one the railing silhouette is drawn in, so keep it LIGHT: it has to hold against open sky between the bars. Taking it near the leg colour flattens the deck-and-legs mass into the rail above it; taking it near the verdigris deletes the centre bay."},"plate":{"type":"color","default":"#8a9498","label":"Leg plate","describe":"albedo of the six tapered bracket legs (and of the cross-braces that appear once the deck is raised). A clear value step BELOW the galvanised frame so the understructure recedes and the deck band reads as the object's waistline. This is salvaged plate of a different batch from the rails \u2014 it is meant to not quite match, which is the kit's whole material story."},"grating":{"type":"color","default":"#5a6468","label":"Deck grating","describe":"albedo of the three grated deck plates \u2014 the walking surface, and the darkest large area on the part. It is dark because open grating over shadow IS dark, and it is a floor rather than a drawn line: it covers the full 1.0 m clear width. Wants to stay a long way below the frame value or the deck stops reading as a hole in the frame; taking it light makes the run look like a solid plank bridge."},"verdigris":{"type":"color","default":"#5fb79c","label":"Verdigris bronze","describe":"albedo of the bronze salvage: every ball finial, the middle plate of each edge beam, and the ENTIRE centre rail bay top to bottom. Deliberately a whole column of the railing rather than an edging, because an accent spread thin never shows at the strategy camera. This is the mint note that stops a galvanised part reading as a grey one, so keep it saturated and clearly greener than the frame."},"rust":{"type":"color","default":"#c2531f","label":"Oxide at the feet","describe":"albedo of the four outer pad feet, where water stands against the bolted foot and the oxide is deepest. WARM orange oxide, the colour that sings against green \u2014 a brown-grey here is the fastest way to miss this kit. Reads clearly darker and much warmer than the bright bloom on the beam ends."},"rustBloom":{"type":"color","default":"#e88c3c","label":"Oxide bloom at the bolts","describe":"albedo of the bright bloom on the outer beam plates at both ends of the run \u2014 the end plates are where one section bolts to the next, so that is where the rust actually bleeds. The lighter, brighter of the two oxide tones; the pair of them is what keeps the weathering from reading as one flat even coat."},"timber":{"type":"color","default":"#b08a55","label":"Timber","describe":"albedo of the three sawn cross battens laid over the deck as non-slip treads, and of the herb planter tub hooked over the rail. The only warm neutral on the part and the thing that stops the deck being a slab of grey: three bright bars across a dark floor. Keep it clearly lighter than the grating under it."},"growth":{"type":"color","default":"#8fcb4a","label":"Leaves","describe":"albedo of the fresh growth \u2014 the wild blades coming up through the pad feet and the herbs in the planter (and the vines that take the railing at derelict). A lighter, fresher green than the moss it grows out of; matched to the moss the blades vanish into their own host and the base reads as a green smudge."},"growthDeep":{"type":"color","default":"#3b7a2e","label":"Moss","describe":"albedo of the moss on the centre bent's two pad feet \u2014 the shaded, damp spot under the middle of the deck, which is where moss really forms and NOT on the walking surface. A real committed green rather than a grey-green, and a clear value below the leaf colour so the blades growing out of it still read as blades."},"wear":{"type":"choice","default":"weathered","label":"Wear","describe":"how looked-after this run is, and it is GEOMETRY, not a repaint \u2014 the triangle count moves across the three and the FOOTPRINT does not. kept: every filigree bar in place, all three battens down, the planter tended, and no wild growth at the feet. weathered (the shipped default): moss on the centre bent's pads and four wild blades pushing up through the feet. derelict: four scroll bars have gone out of the two outer bays so you can see daylight straight through the top band, one batten has rotted away, and eight vine leaves have taken the centre railing. Still sunlit and being reclaimed by green, never grim.","affects":"geometry","options":["kept","weathered","derelict"]},"piece":{"type":"choice","default":"straight","label":"Piece","describe":"which piece of a catwalk run this build is. Every value keeps the SAME 4.00 m deck, the same flush square ends and the same rail cross-section at the joint, so any value butts against any other. straight is the through section. end-stop closes the +X end with a rail across the deck and two bars under it, i.e. the far end of a run where it stops in mid-air. access-gap takes the centre bay of the +Z railing out, rails and all, leaving the posts standing \u2014 the landing where a ladder or a stair arrives at the deck.","affects":"geometry","options":["straight","end-stop","access-gap"]},"railStyle":{"type":"choice","default":"filigree","label":"Rail infill","describe":"what fills each rail bay between the posts, top rail and mid rail. filigree is the reference ironwork: a scroll pair sweeping up to the top rail over a pair of turned uprights, with the centre bay drawn as a lyre and a cross. balusters is the plain fabricated version \u2014 three straight uprights per band, the run the village put up in a hurry. salvage-panel fills each bay with one flat sheet of scrap plate instead, so the railing goes solid and the run reads as a walled gantry; it is also the cheapest build in triangles.","affects":"geometry","options":["filigree","balusters","salvage-panel"]},"deckHeight":{"type":"range","default":0.6,"label":"Deck height","describe":"height of the kerb top above the ground in meters \u2014 how high off the ground the catwalk runs. 0.60 m is the default off the refs, a low gantry you step onto. 3.00 m is exactly one kit storey, so the deck lands on a first-floor eave line. It REBUILDS rather than scaling: the legs are the only thing that gets longer, their section, their bracket heads and their pad feet all stay exactly the same size, and once a leg passes 1.30 m the outer bents gain a full cross-braced BAY at a frozen 1.30 m pitch (one bay from about 1.55 m, two from about 2.85 m), so the triangle count moves with the knob. The handrail stays 1.00 m above the deck at every value, per the kit contract.","affects":"geometry","min":0.6,"max":3},"deckWidth":{"type":"range","default":1,"label":"Deck width","describe":"clear walking width between the two kerbs in meters: 0.80 m is a tight single-file service catwalk, 1.00 m is the default off the refs, 1.60 m is a wide gantry two people pass on. Strongly changes the end-on and front silhouettes. A catwalk has nothing REPEATING across its width \u2014 one batten spans it whatever it measures \u2014 so this knob honestly changes lengths only: the beam section, the post section, the rail section, the leg section and the pad feet all stay put and the deck plates, the battens and the bracing simply get longer, exactly as a real fabricator would build it.","affects":"geometry","min":0.8,"max":1.6}},"presets":{"galvanised-verdigris":{"iron":"#b6bfc2","plate":"#8a9498","grating":"#5a6468","verdigris":"#5fb79c","rust":"#c2531f","rustBloom":"#e88c3c","timber":"#b08a55","growth":"#8fcb4a","growthDeep":"#3b7a2e"},"oxide-run":{"iron":"#d2703a","plate":"#b4652e","grating":"#3a2c21","verdigris":"#3e8f7c","rust":"#9e3b18","rustBloom":"#e88c3c","timber":"#8a6236","growth":"#5ea83a","growthDeep":"#24552a"},"mint-paint":{"iron":"#b7e4ce","plate":"#8fd3b6","grating":"#5a6468","verdigris":"#3e8f7c","rust":"#c2531f","rustBloom":"#e88c3c","timber":"#d9c9a3","growth":"#8fcb4a","growthDeep":"#3b7a2e"},"brass-works":{"iron":"#e3b34a","plate":"#b08a55","grating":"#5c4028","verdigris":"#5fb79c","rust":"#a8412f","rustBloom":"#d2703a","timber":"#f2e6c8","growth":"#8fcb4a","growthDeep":"#3e8f7c"}},"rev":1792408798,"preview_v":1792459719,"mod_v":1792408798}
