Ink-plum (墨梅) is a Song-dynasty literati tradition: plum blossoms drawn strictly in monochrome ink, their petals never coloured but reserved — left as the bare silk showing through thin outlines, while branches are graded washes in "ink's five tones." The surviving scrolls have aged to a warm tea-stained tan, never bright white. This system rebuilds that restraint as an interface: a single diagonal branch, vast empty ground, hairline dividers, and a calligraphic colophon column. Space carries as much weight as mark. Nothing is loud; everything breathes.
