/* ============================================================
   GPSHUB Panels — design system común de los drawers laterales
   (Historial / Búsquedas / Zonas; rediseño Fase 3). Mismo lenguaje
   visual que el panel de Flota (fleet-panel.css): borde azul grueso,
   header azul sólido con título/ícono blancos, tipografía Segoe,
   azul = activo, verde = "en línea".

   Las variables :root (--ghc-*) viven en map-control-panel.css y NO
   se redefinen acá. Se reutilizan primitivos ya globales del sistema
   (definidos en fleet-panel.css): .ghc-iconbtn, .ghc-search* y
   .ghc-empty. Lo de acá son las piezas que esos paneles no tenían:
   shell de drawer genérico, campos de formulario, botones, grupos
   colapsables, sub-filas y toggles on/off.
