{"params":{"colorway":{"type":"choice","default":"brass-tendon","label":"Colorway","describe":"curated kit-coherent scheme, each carrying three of the kit's metals plus the jewel so the fittings never share a hue with the chain running between them: brass-tendon is a brass chain on a dark-iron anchor with a polished steel head, a bronze ring, a copper swivel and an amber cabochon; copper-tendon a warm copper chain on near-black iron with a brass ring and a cold iron swivel; cold-iron an all-grey steel chain and fittings with the amber left as the only warm thing on the part; gilt-ruby a bright gold chain on bronze and iron with a ruby in place of the amber","options":["brass-tendon","copper-tendon","cold-iron","gilt-ruby"]},"chain":{"type":"color","default":"#B8860B","label":"Chain","describe":"albedo of every link of the chain and nothing else. The dominant mass on the part \u2014 more than half its triangles \u2014 and the thing it reads as from across a room; brass by default. Keep it a clear value step from the anchor plate it runs off, or the chain stops separating from its own mount"},"stud":{"type":"color","default":"#E1E1E1","label":"Stud head","describe":"albedo of the anchor's slim post and the head that tops it (ball, cog or nut) \u2014 the turned fitting the chain's first link is threaded on and held captive by. Polished steel by default and deliberately BRIGHT, because it stands on the darkest zone on the part and is the one blob the eye lands on at the wrist end"},"plate":{"type":"color","default":"#4F5D75","label":"Anchor plate","describe":"albedo of the hexagonal foot plate bedded on the back of the hand and the boss standing on it. Dark iron by default: this is the structural, darkest and coolest zone on the part, and its job is to be the land the bright head and the steel rivets are framed against. Lighten it and the anchor stops reading as ironwork"},"band":{"type":"color","default":"#CD7F32","label":"Ring","describe":"albedo of the band round the middle finger's first phalanx and nothing else, so the ring can be re-metalled without touching the chain or the swivel bolted to it. Bronze by default, one clear value rung above the copper swivel that stands on it"},"swivel":{"type":"color","default":"#C04000","label":"Swivel","describe":"albedo of the whole swivel casting: the chamfered saddle on the ring, the turning housing, its shoulder collar, the leaning eye that carries the chain's last link, and the bezel round the cabochon. One knob because those pieces are one casting. Copper by default and kept DARK on purpose \u2014 it is the setting the amber is framed in"},"rivet":{"type":"color","default":"#A9A9A9","label":"Rivets","describe":"albedo of the four domed rivet heads set in a rectangle round the boss on the anchor plate's deck, and nothing else. Steel by default and deliberately COOL, which is what stops them competing with the cabochon at the other end of the part"},"lens":{"type":"color","default":"#FFD166","label":"Cabochon","describe":"albedo of the faceted stone set in the swivel's bezel \u2014 the jewel bearing, the kit's one lit detail and the only zone this asset declares in `night`. It has a hex of its own so a consumer can light the jewel by albedo without lighting the copper it is set in; nothing else on the part may ever be given this colour"},"hand":{"type":"choice","default":"left","label":"Hand","describe":"which hand the chain is hung for. Right is the exact mirror \u2014 the anchor, every link and the swivel with it \u2014 so it lies on a tracked right hand's middle finger the way this one lies on a left.

The part is re-solved rather than scaled: the anchor plate's underside is re-bedded on the hand's own dorsal surface (the extensor cord standing on it included), the ring is re-cut to the finger's real section, and the whole chain line is lifted onto the new crown. The MADE stock is identical at every value \u2014 the same 15 mm plate, the same 4.7 mm ball head, the same 1.16 mm wire, the same 0.4 mm chamfer \u2014 so the triangle count does not move with this knob","affects":"geometry","min":0.85,"max":1.3,"step":0.05},"knuckles":{"type":"range","default":1,"label":"Knuckle relief","describe":"how bony the joints of the hand underneath read, 0.3 smooth and 1.6 every knuckle a knob. It matters here because the chain crosses the middle knuckle at its highest point: the run takes the higher of the back of the hand and the finger's own crown at every station, so a swollen knuckle lifts the middle of the chain over it and the links either side ride up to follow, instead of the knuckle pushing through the run","affects":"geometry","min":0.3,"max":1.6,"step":0.1},"reach":{"type":"range","default":1,"label":"Reach","describe":"how far back along the middle metacarpal the anchor stud is set, and so how long the chain is. 0.72 pulls it up to 23 mm behind the knuckle for a short eleven-link run that barely leaves the finger; 1.0 the reference, the stud 32 mm back and thirteen links at a 4.0 mm pitch; 1.24 sets it back toward the wrist on a fifteen-link run that crosses most of the back of the hand. The chain is REBUILT at the new length \u2014 it gains links two at a time at a constant pitch, and the plate, the head and every fitting keep their own millimetres \u2014 so the triangle count moves with this knob, 964 to 1156","affects":"geometry","min":0.72,"max":1.24,"step":0.04},"gauge":{"type":"range","default":1,"label":"Chain gauge","describe":"the chain's stock over the same run, from fine jewellery chain to a working one. 0.82 is fifteen fine links at a 3.4 mm pitch on 0.99 mm wire; 1.0 the reference, thirteen links at a 4.0 mm pitch on 1.16 mm wire, each link 7.5 by 4.5 mm; 1.5 nine heavy links at a 5.9 mm pitch on 1.72 mm wire, individually countable from across a room. Link length, width, wire and count all come off ONE pitch, so the run stays correctly interlocked at every value, and the anchor post grows to suit the heavier stock it has to hold","affects":"geometry","min":0.82,"max":1.5,"step":0.04},"head":{"type":"choice","default":"ball","label":"Stud head","describe":"what tops the anchor post and keeps the chain's first link captive on it \u2014 the one blob the eye lands on at the wrist end of the part. `ball` is a 4.7 mm faceted ball, the reference and the roundest silhouette; `cog` a six-toothed shop cog 5.4 mm across that breaks the outline into teeth and is the most obviously clockwork of the three; `nut` a plain chamfered hexagonal nut, the flattest and most workmanlike.
