/**
 * Buttons Component v3.0 - Unified Global Button System
 *
 * Einheitliches Button-System fuer alle Seiten und Viewports.
 * BEM-Naming (Block-Element-Modifier) mit Backwards-Compat.
 *
 * ARCHITEKTUR:
 * - .btn               -> Basis (Sizing, Layout, Typography)
 * - .btn--primary       -> Farbvariante (nur Farben)
 * - .btn--lg            -> Groessenmodifikator
 * - .btn--block         -> Utility-Modifier
 *
 * TRICK: border: 2px solid transparent auf ALLEN Buttons
 * -> Outline/Ghost haben identische Aussenmasze wie Primary
 * -> Keine Padding-Kompensation noetig
 *
 * BACKWARDS COMPAT:
 * Single-Dash (.btn-primary) und Double-Dash (.btn--primary)
 * werden beide unterstuetzt. Neue Templates sollen BEM verwenden.
 *
 * @package SLV_Transporte
 * @version 3.0.0
