Button

Source: client/lib/theme/vueda-tailwind/controls/index.js

The pressable root. Composes _ButtonBase.root plus the _Button* primitive for the resolved (tone, emphasis) cell (see controls/button/buttonVariant.js), then layers the per-size height / padding pair from base.css § Control sizing (or size-vueda-control* for icon-only sizes). The link emphasis skips the control-height block and goes inline. The data-state=cooldown state (set by the component while a one-shot action is recovering) mutes the label to --muted-foreground and suppresses hover so a recently-clicked button reads as "wait" without changing layout.
