Iconography draft v0.2.1

The icon font, the one style every icon is drawn in, its sizes and colors, and when an icon needs a name.

Icons are glyphs of Material Symbols Outlined, an icon font: a component names an icon by its ligature name and the font draws it. The font is variable; the system fixes its axes (fill, weight, grade, optical size) to a single style, so every icon looks the same in every component. The Figma library has no icon tokens: the font and its axes (font.icon.*) are the design system's additions, read directly by components. Icons take their size from the size scale and their color from the text next to them.
