/* RJ-42 - painel do looper de rack (inspirado no Lexicon PCM42)
 * Carregar depois de vendor/dcx-core/css/base.css.
 * O 42 usa o mesmo painel do RJ-950 (botoes, legendas, LCD, drive, jacks):
 * a primeira parte sao as regras .r9-* que ele usa, copiadas do rj950.css, escopadas em :where(.r42)
 * (mesma especificidade de antes; nao vazam para o #r9 quando o Studio carrega os dois CSS).
