 * Disabled (toggled-off) effect drawer — issue #1758.
 *
 * When an effect is off, `.fx-disabled` is set on its `.fx-section` (by the
 * power-dot handler in audio-enable.js). We dim the expanded controls and the
 * effect name so the off state is unmistakable, while keeping the power dot and
 * header fully bright so re-enabling stays obvious. We deliberately do NOT set
 * `pointer-events: none`: the off-state controls must still be adjustable
 * (e.g. the compressor crossover / G_EQ curve preview, issue #650), and the
 * dimming is applied only to the expanded content so the collapse transition is
 * unaffected.
