/* ROBERIN energy-converter (에너지 단위 변환기) - The New workspace v3 (20260716b)
 * Scope: .tn-enc-* only. Full-width composition: 좁은 좌우 split + 세로로 긴 16단위 표를 폐기하고
 * 전체 폭을 채우는 상하 밴드로 재구성 — 입력 밴드(전체 폭) / 결과(J 히어로 | 에너지 스펙트럼 좌우) /
 * 16단위 4열 그리드(가로로 펼쳐 짧게) / 실생활 비교 3열.
 * Gates: realtime (#17), fills usable width no idle pane (#15/#28), container gap (#22/#37),
 * no decorative rail (#30), custom select chevron (#33), flipped dark + text-fill (#8/#14),
 * quiet flat wash (#27), element reset li/ul/ol/dd only (#37). */
