{"params":{"colorway":{"type":"choice","default":"dusty-marram","label":"Colorway","describe":"Curated kit-palette schemes, named and coloured as on the kit's marram dune tile so one word dresses both. dusty-marram is pale warm sand under the kit's dusty blue-green marram with yellow straw tips and a grey-brown runner. high-summer is deeper golden sand under a stronger green with pale tips and a dark runner. grey-shore is a cool overcast northern dune with khaki tips. bleached-dune is sun-whitened sand under a pale sage marram.","options":["dusty-marram","high-summer","grey-shore","bleached-dune"]},"tide":{"type":"range","default":0.5,"label":"Tide","describe":"The kit-wide water knob. The sea never reaches a dune tuft, so here it is the wind that comes with the water. 0 is a still morning: every blade stands near upright and the fan is even all round. Rising toward 1 (high water in a blow), the blades lean further downwind (toward -X) and their tips bend with it, until at 1 even the upwind blades have turned over and the whole tuft streams one way. From 0.5 the collar is scoured too: its windward side is cut down to a steep scarp of darker damp sand, and its lee side heaps into a crescent tail downwind, full size at 1. The ambient sway grows with it.","affects":"geometry","min":0,"max":1,"step":0.1},"weather":{"type":"range","default":0.6,"label":"Weather","describe":"The kit-wide salt and sun knob. It bleaches marram to straw one blade at a time. First the tips of the tall blades go (most of them by 0.5), then the medium blades' tips, and from 0.4 whole outer leaves die back. 0 is every blade blue-green. 1 has every tip straw and over a third of the blades died back whole, so the tuft reads yellowed. The sand and the runner never change. Changes no geometry.","min":0,"max":1,"step":0.1},"tallness":{"type":"range","default":1,"label":"Tallness","describe":"How long the blades have grown. 1 stands the tallest tip about 0.93 m up. 0.7 is a squat young tuft about 0.69 m tall with stiff straight tips; 1.3 is a rank old one about 1.17 m tall whose longer, heavier tips arch further over. Blade lengths and tip droop change; the crown, the collar, the runner, the blade widths and the number of blades stay fixed, so a tall tuft reads slender and a short one stubby, which scaling the whole tuft cannot give.","affects":"geometry","min":0.7,"max":1.3,"step":0.05},"tillers":{"type":"range","default":18,"label":"Tillers","describe":"How many shoots the crown carries, each a bundle of five blades (one tall, one medium, three splayed). 10 is a young tuft of 50 blades on a crown about 0.5 m across with a small collar. 18 is the default, 90 blades on a crown about 0.65 m across. 26 is an old, dense clump of 130 blades on a crown about 0.8 m across. New tillers only ever join at the outside, so the inner ones never move, and the collar grows with the crown.","affects":"geometry","min":10,"max":26,"step":1},"runners":{"type":"range","default":0,"label":"Runners","describe":"How many rhizomes break the surface. 0 is none, a tuft on its own. 1 is the single stepped runner lying out from the collar toward -X and the front. 2 adds a second on the windward side toward +X and the back. Each is about 0.3 m of segmented brown stem tapering to a point, lying on the ground.","affects":"geometry","min":0,"max":2,"step":1},"sand":{"type":"color","default":"#E8D9B5","label":"Sand collar","describe":"Albedo of the collar of heaped sand round the crown: its crest, its flanks and its underside.

Keep it a clear step darker than the sand so the tuft reads from across a beach."},"bloom":{"type":"color","default":"#D7DFDC","label":"Leaf bloom","describe":"Albedo of the flat smooth face of every living blade, the one that faces into the tuft, with the waxy blue-grey bloom of a marram leaf. Paler and bluer than the ribbed faces; it shows through the gaps and on the far side of the fan."},"straw":{"type":"color","default":"#EDD68F","label":"Straw","describe":"Albedo of sun-bleached marram: the tips of the blades and the whole outer leaves that have died back, which the weather knob turns on one blade at a time.
