/**
 * Fancy Text Studio — shared base styles for every module (generator, case
 * converter, …): colour tokens + dark mode, utilities, labels, the input
 * and buttons. Module stylesheets depend on it (handle fts-core).
 *
 * Every rule is scoped under .fts-wrap and every class is prefixed .fts-,
 * so themes (Kadence, Astra, …) and other plugins cannot collide with it.
 * Theme button styles are reset explicitly on our buttons.
