/* ============================================================
   Sionic Tech Blog — 작성글 시작 화면 공용 모듈 (단일 소스)
   브레드크럼 · 작성자 메타(아바타·칩·날짜·태그·다크 토글) · 문서 내용 듣기(TTS)
   함께 사용: assets/post-meta.js + window.SIONIC_POST_META 설정
   스킬은 이 모듈을 갖다 쓰고, 이 UI를 글마다 다시 만들지 않는다.
   테마 변수(--si-*)가 없는 페이지에서도 동작하도록 fallback을 둔다.
