 * Scoped reset. MasterStudy and most WP themes style bare <button> globally with
 * their own padding, min-width, font-size and text-transform. Without neutralising
 * that first, the tab strip inherits theme padding and overflows the panel.
 * Everything below is re-declared explicitly rather than relying on defaults.
