# Collaplex 32 段 EQ + 总音量 —— 本文件由 脚本/安装.sh 生成(占位符 __EQ_WRAPPER__ / __TARGET__)
# 链路: ... -> HRTF 核心 -> [本图] 32 段 EQ + 总音量(pipe DSP) -> 数字输出
#
# ★ __TARGET__ 是**用户选定的输出设备**(落盘在 ~/.local/state/cinema-spatial/output.json,
#   面板「输出设备」卡片可改; 没选过则由安装脚本探测第一个数字输出)。
#   设备名跨重插是稳定的(含 USB 序列号), 所以设备晚到也不改这一行 —— 由面板守护
#   (web/output_route.py)在设备出现后自动把它挂上去。
