KaKa SQA — design system v7 · 「LIQUID STUDIO / 液态工作台」
The signed-in content rooms of the liquid-glass brand (front.css v12):
same graph paper, same ink, same three inks in the tray (acid / blue / red),
same glass — tuned to working volume for directories, files and calculators.
Class names & variable names are kept from the daybreak build so every page
adapts automatically.
