/* ==================== SIGNAL — broadcast instrumentation ==================== */
/*
   Design grammar:
   • Oscilloscope hero — name over a deterministic waveform trace, faint
     graticule, tuner dial; the whole page glows through scanlines
   • Productions as frequency bands: ident code / sparkline / title / kHz
   • One image resolved into vertical spectrum slices with stagger reveal
   • Further images as monitor stills; tracks as the ON AIR programme
   • Test-card sign-off
   Display voice: Archivo Black caps. Instrument voice: DM Mono.
   All selectors scoped to .pg-signal. Infinite animations self-gate behind
   prefers-reduced-motion: no-preference.
