/* =====================================================================
 * Toast — bottom-center slide-up, studio language
 * ---------------------------------------------------------------------
 * 별도 파일로 분리한 이유: studio main 페이지(main.modal.css 로드)와
 * studio editor 페이지(editor.css 로드)는 서로 다른 CSS 번들을 사용한다.
 * 토스트 알림은 두 페이지 모두에서 필수이므로 양쪽 모두 이 파일을
 * 추가로 link 한다 (studio/index.ejs 참고).
 *
 * 변경 시 주의: editor.js / main.js 가 동일한 `#toast-container`
 * 마크업과 `.toast`, `.toast-show`, `.toast-hide` 클래스 시퀀스를
 * 사용하므로 이름을 바꾸려면 양쪽 JS도 함께 손봐야 한다.
