Radii

Four steps, used consistently — crisp corners are half of what makes the system feel engineered rather than decorated.

The scale

	Token	Used by
	--auri-shape-sm · 6px	badges, delta chips, small controls
	--auri-shape-md · 10px	buttons, inputs, callouts, code insets
	--auri-shape-lg · 14px	cards: Stat, Chart, DataTable, ApprovalCard, CodeBlock
	--auri-shape-pill	progress tracks only

The rule

Radius follows role, never taste-per-component: a chip is 6px whether it lives in a Stat or a Badge; a card is 14px whether it holds a chart or a decision. The base step (10px) is adopted from shadcn/ui v4's 0.625rem; the scale is one notch tighter and one notch looser around it, and nothing else.
