Foundations
The rules that hold on every surface. Read these first: every component and every pattern rests on them.
The surfaces, the inks, the one accent and the status colours, each with its reason.
The faces, the scale and when text is mono.
The steps between blocks and the page frame they stand in.
What a control does under the pointer, and what a page says when it has nothing to show.
The standard every text follows, and the limits a check holds.
Contrast, the keyboard and reduced motion, and what the checks cannot see.
