Tokens, components and the written rules that keep them honest — delivered as code, not a slide deck about code.

Clickable builds at real fidelity, so the argument happens over something concrete instead of a static frame.

Focus order, contrast and reduced-motion behaviour designed in from the first screen rather than audited at the end.

Annotated source, a component catalog and a short recording of the reasoning, so the decisions outlive the project.

The small stuff — what a control does under a pointer, under a finger, and for someone who has asked for less movement.

Route and state changes that keep the reader oriented, with a clear origin and destination for everything that moves.

Compositor-friendly properties, measured on a mid-range phone rather than on the machine that authored it.
