The Go board — 碁 in Japan, 围棋 in China, 바둑 in Korea — is the defining surface of East Asian board-game culture: a 19×19 grid of thin black lines hand-drawn in urushi lacquer across the warm golden heartwood of a polished kaya goban.
Its aesthetic is one of extreme minimalism — bare wood as negative space, two stone colors, and the brush-record clarity of kifu game records. This system distills slate-black, clamshell-white, and honey-gold kaya into a digital language of austere flat wood and thin precise lines.
围棋盘——日本称「碁」「囲碁」，中国称「围棋」，韩国称「바둑」——是东亚棋类文化的标志性界面：在打磨光润的榧木（kaya）温暖金黄心材之上，以生漆手绘出 19×19 道纤细黑线，九处星位点缀其间。
它的美学是极致的极简：裸木即留白，黑白两色棋子是仅有的两个图形，棋谱（kifu）记录则带着毛笔书写的清晰。本设计系统将那慈黑（Nachiguro）板岩的黑、蛤白（hamaguri）的暖白，与蜜糖金黄的榧木融为数字语言——质朴的平木底色、纤细精准的漆线，以及大面积的呼吸留白。
