/**
 * Page Designer — Link Settings Panel — dedicated styles
 * v1.0.0 (introduced in PAGE_DESIGNER_VERSION 2.6.48)
 *
 * Right-side slide-out rail for link component settings. Uses a 100%
 * dedicated `.pd-lnk-pnl-*` namespace. Panel chrome rules are
 * deliberately DUPLICATED locally instead of reusing `.pd-dsp-*` or
 * `.pd-img-pnl-*` — honours the "no shared CSS classes" rule.
 *
 * Every selector in this file is prefixed `.pd-lnk-pnl-`. No overlap
 * with `.pd-dsp-*`, `.pd-typ-*`, `.pd-img-pnl-*`, `.pd-blk-*`, or
 * any other tool's namespace.
