/* WaifuStudio — Estilos Base y Layout Principal
 * Qué hace: variables :root, tipografía, reset de scrollbars, estructura de paneles y topbar.
 * Qué no hace: no define componentes interactivos ni vistas particulares de pestañas.
 * Dependencias: ninguna (hoja de estilos raíz cargada en primer lugar).
