Bare-WebGL components built for this site — point-cloud figures you can grab and spin, tuned to the same paper-and-ink palette as everything else. No frameworks, no model files: geometry is generated parametrically and rendered as dots, in the spirit of Ciechanowski’s explainers but reduced to the site’s own visual language.
One program per figure, point sprites, colors read live from the same CSS custom properties that drive the light and night editions. Source: /static/fig.js.
