/**
 * Button
 *
 * The whole action surface of Foundry in one component. It is intentionally a
 * *shared* component (no `'use client'`): rendered from a Server Component it
 * ships zero JavaScript, and it upgrades to a client island automatically when
 * a Client Component imports it.
 *
 * Height, padding and radius resolve from density and radius tokens, so a
 * button restyles itself when the density or palette axis changes. Focus is
 * handled once, globally, by the `:focus-visible` rule in `globals.css`.
