One uniform straw tone by design; every tonal difference on the roof comes from lighting, not from paint"},"timber":{"type":"color","default":"#8c6a4a","label":"Rafters & posts","describe":"albedo of the secondary timber: principal and common rafters, the king posts, the diagonal struts and the eave wall-plates. Mid brown \u2014 one value step lighter than the heavy beams so adjacent members separate under flat shading"},"beam":{"type":"color","default":"#6f4e37","label":"Heavy beams","describe":"albedo of the primary timbers: the flat ridge beam that projects past both gables, the truss tie beams resting on the wall top, and the collar ties.

It REBUILDS rather than stretches: the 4 m roof gains a third king-post truss at the mid-module joint, four more common rafters at the same 0.50 m pitch, and twice the thatch stations, so the straw clumps stay the same size instead of being smeared out. Member sections, the 45\u00b0 pitch and the eave line are identical at both values","affects":"geometry","options":["1","2"]},"courses":{"type":"range","default":4,"label":"Thatch courses","describe":"how many overlapping straw courses are laid down each slope, ridge to eave (whole numbers 3-5). Each course is a run of thatch parallel to the roof plane that rolls up into a lip overhanging the course below, and every lip carries its own irregular row of ragged straw ends; 3 gives three deep bold laps, 5 a finer stack. The 45\u00b0 pitch, the thatch thickness and the eave line do not change","affects":"geometry","min":3,"max":5},"lip":{"type":"range","default":1,"label":"Course lip roll","describe":"how far each course rolls out over the one below, as a multiple of the standard 0.095 m lip: 0.5 = a tight, almost flush lap with a crisp slope; 1.5 = fat rolled straw with a deep shadow under every course. The roll gets a proportionally longer run-up as it grows, so the lip never lies back into a horizontal terrace; thatch thickness, pitch and eave line are unaffected","affects":"geometry","min":0.5,"max":1.5}},"presets":{"golden-thatch":{"straw":"#b89b72","timber":"#8c6a4a","beam":"#6f4e37"},"fresh-straw":{"straw":"#e8dcc0","timber":"#8c6a4a","beam":"#6f4e37"},"mossy-thatch":{"straw":"#7d8a5a","timber":"#8c6a4a","beam":"#6f4e37"},"painted-frame":{"straw":"#b89b72","timber":"#9a3b32","beam":"#6f4e37"}},"rev":1786122369,"materials":{"straw":{"kind":"foliage","finish":"moss"},"timber":{"kind":"wood","finish":"raw"},"beam":{"kind":"wood","finish":"raw"}},"materials_note":"what each colour zone is made of: `kind` and `finish` name a procedural PBR material in https://polyfork.dev/materials.mjs (dressByAlbedo finds a zone by its albedo in COLOR_0).
