/**
 * VINTAGE RADIO THEME
 * 
 * Layout Philosophy: The radio cabinet is a rigid physical object.
 * All elements occupy fixed positions. Hiding an element fades it
 * to invisible without collapsing or repositioning anything.
 *
 * !important Usage: Restricted to Section 5 (Hidden State Neutralizer)
 * where we must override base stylesheet combinatorial hidden-state
 * rules that collapse and reposition elements.
