 * Peek's Button (2026-08-28), verbatim, plus what Ship added and Peek should
 * adopt: a `destructive` variant — the muted button in the error colour, for
 * "Delete project" and its kind; a destructive action is a button like any
 * other, not a dotted link — and `type="button"` by default, so a button
 * inside a form submits it only when asked to. On Base UI's Button since
 * stage 2 of the migration (2026-09-07).
 *
 * Three variants and two sizes: 32px default / 24px small, 6px radius, 500
 * weight. The sizes are the `btn-default` and `btn-small` type tokens.
 *
 * The primary reads in `text-inverse` on the accent — a theme decides what
 * that is (dark on Peek's light accents, light on Ship's dark one). Under
 * Signal it is also semibold, as Peek has it.
 *
 * `disabledReason` is the package's own rule, "only offer actions that can
 * succeed", done once: the button is disabled, stays reachable by keyboard
 * (Base UI's `focusableWhenDisabled`), and shows the reason as a tooltip on
 * hover. Ship wrote that wrapper by hand six times.
 */

 * was missing was only the *type* saying so, which is enough to stop a caller.
 *
 * It matters because a Base UI part composes through `render`: at stage 4 a
 * `Menu.Trigger` or a `Dialog.Close` **is** this Button rather than wrapping
 * one, and a trigger that cannot be measured or focused is not a trigger.
