Straight branches can be intentional.","recipe":["Preserve baseline PNG/JSON and valued qualities; compare the reference at matched subject size.","Plan dominant limbs and subordinate forks before fine texture. Use unequal fork heights, spans and branch roles; aim tips toward intended foliage masses.","Paint open centerlines. Round turns locally according to branch role, avoiding repeated elbows or a uniform global curve.","Choose visible branches before painting. Connect children to painted parent paths and reduce subordinate width. Do not excuse detached fragments as leaf occlusion.","Inspect overlap at roots. Compare lighter initial contact, then parent-compatible pigment/contact separately. Pressure onset alone had little effect here.","Review bare branches and the whole tree. Test pressure rhythm or drier contact only after structure; reject vanished branches or floating foliage."],"decisions":{"fineJitter":"rejected: preserved the old large-scale fan","highForksWithRepeatedElbows":"partial: improved exposure but angular repetitions were rejected","omissionOnly":"partial: reduced clutter but left a conspicuous bare sideways branch","lightPressureOnsetOnly":"small visual effect; not a sufficient joint repair","refinedStructureAndContact":"adopted locally: foliage-directed flow, unequal roles, paler main limbs and narrower subordinate contacts","pressurePlusDryContact":"rejected: dry .73/.83 on these narrow paths broke branch continuity","pressureOnly":"rejected as additional complexity: continuity returned, but visible improvement was small"},"limits":["Example is an independent bare-branch swatch, not an artwork overlay or a universal tree template.","Keep v3 default; v4 requires the explicit material trial guide.","Wet/dry and width numbers depend on contact and paper.

Bare-space simplification is not physical leaf occlusion.","Matching final material time does not match every deposition time; waits affect the whole sheet.","Foliage/trunk/grass commands and runtime were preserved.
