/* 관제 화면 공용 단추 겉모습 — Lucian UX/UI Prompt 를 옮김
 * MIT License (c) 2026 Seokwoooo · https://lucianlabs.dev/uxui-prompt/
 *
 * 모든 관제 화면이 자기 <style> 뒤에 이 파일을 건다(/assets/lucian.css).
 * 여기에는 <겉모습>만 둔다 — 높이 · 안쪽 여백 · 폭은 화면마다 다르므로 각 화면의 규칙이 정한다.
 * 색은 화면마다 정의된 변수(--accent-btn · --accent-hover · --accent-on …)를 쓴다.
 * 바탕을 칠하는 것은 주 단추뿐이다 — 보조 · 위험 단추의 바탕은 각 화면이 정한다
 *   (위험 단추의 「한 번 더 누르면 지움」 바탕을 덮지 않으려고).
 * 글자 대비: 주 단추 그러데이션은 --accent-btn 에서 더 어두운 쪽으로만 간다(흰 글자 4.9:1 이상).
