/* Design direction: dancheong, the painted woodwork of Korean palaces and temples.
   Colours are Seoul's official colour set (seoul_color_10 sheet, Hex Code Web):
   dancheong red 941e34, Namsan green 455f54, Seoul sky 6789ca, ginkgo yellow e5b560, kkotdam ochre bc6f25, palace brown 594743.
   Patterns in ../img are drawn for this site: a lotus band and corner rings in the manner of dancheong, and a chilbo (seven treasures) ground, drawn large and faint so it stays quiet.
   Type: Noto Serif KR for reading, Chosun Gungseo (palace brush style) for the Hangul itself. */
