{"params":{"colorway":{"type":"choice","default":"treated-timber","label":"Colorway","describe":"Curated kit-coherent scheme. treated-timber is the approved build: a mid-brown tanalised kerb round pale sand, grey precast apron, true-white board and red plasticine. weathered-grey silvers the kerb timber to a warm grey and lays a new pale concrete apron, a pit that has stood several winters, with a brick-red indicator. creosote-dark takes the kerb to a dark brown round pale silver sand on a darker cool-grey apron, the highest-contrast frame. track-apron lays the apron in the running track's brick red, as if the runway surface carried on up to the pit, with a pale grey indicator strip. Every scheme keeps the board the kit's true white and never uses the kit accent blue.","options":["treated-timber","weathered-grey","creosote-dark","track-apron"]},"matchday":{"type":"range","default":0.6,"label":"Matchday","describe":"Whether there is a meeting on, spent on the sand and the board and never on a tint. At 0 and 0.1 (a wet Tuesday) the sand is raked dead flat just under the kerb and a dark painted steel cover plate lies over the take-off board and its plasticine. From 0.2 to 0.7 the plate is off and the sand is heaped into a raked crown standing proud of the kerb, with footfall craters at the far (landing) end: one crater at 0.2, one more per step, five at the 0.6 default and six at 0.7. From 0.8 to 1 a competition is on: the crown is raked out into ridges running the length of the pit, broken round one deep heel pit where the last jumper landed, and the plasticine carries a toe scuff. The kerb and the paved apron are the same build at every value.","affects":"geometry","min":0,"max":1,"step":0.1},"pitLength":{"type":"range","default":6,"label":"Pit length","describe":"Length of the sand box along the run, kerb outside to kerb outside, in metres: 6 is the approved school-ground pit, 9 a full senior competition pit. It rebuilds rather than stretches: the 0.15 m kerb section, the 3.0 m width, the crown shoulders and the apron are identical at every value, the long kerb is laid in more timber lengths (never longer than 3 m each) as the box grows, and the footfall craters and heel pit stay the same distance from the far kerb, so a long pit shows more clean raked sand between the board and the landing marks.","affects":"geometry","min":6,"max":9,"step":0.5},"boardDistance":{"type":"range","default":1,"label":"Board distance","describe":"How far the take-off line (the board's pit-side edge) stands from the sand, in metres: 1 is the approved school setting, 3 the senior one. The paved apron grows with it, always ending 0.45 m past the board so the footprint stays on the 0.5 m grid; its side slabs are laid in rows of about half a metre at every value and the runway strip in front of the board in slabs of at most a metre. The board, the plasticine, the kerb and the sand box do not change.","affects":"geometry","min":1,"max":3,"step":0.5},"kerb":{"type":"color","default":"#8b5e37","label":"Kerb timber","describe":"Albedo of the treated-timber kerb frame round the sand: all four sides, their chamfers and their outer faces.
