/**
 * Canonical Luna push button (#99 / #78), value-for-value identical to the
 * xp.css `button` rules so hand-rolled buttons and xp.css-styled native
 * buttons look the same everywhere:
 *
 *   border: 1px solid #003c74; radius 3px;
 *   face:   linear-gradient(180deg, #fff, #ecebe5 86%, #d8d0c4);
 *   hover:  orange inner glow; active: pressed gradient;
 *   focus:  1px dotted outline inset.
 *
 * Previously XPAlert, XPConfirm, PasswordDialog and XPInput each duplicated
 * a flat #ECE9D8 button that matched neither xp.css nor each other.
