/* HermesCustom CSS — Lukas' responsive-layout + Mobile-Toggle-Pattern.
 *
 * Loaded via <link rel="stylesheet"> in vault.html.
 * Applied at first paint (no FOUC).
 *
 * LAYOUT PHILOSOPHY (v0.5):
 *   - Desktop ≥1025px: 3-panel layout, tree visible, graph visible
 *   - Tablet 600-1024px: 2-panel compact, tree visible OR graph visible
 *     via "Show Graph" button toggle (starts hidden)
 *   - Mobile <600px: single column, tree as hamburger, graph as FAB → modal
 *
 * The key UX change vs v0.4: Graph is NEVER in bottom panel on Mobile
 * (waste of vertical space). It's a toggle button → full-screen modal.
