/* HermesCustom CSS — Lukas' responsive-layout additions for obsidian-web-viewer.
 *
 * Loaded via <link rel="stylesheet"> in vault.html (one-line patch)
 * BEFORE obv's main <style>, so that our rules apply at first paint
 * (no FOUC, no layout shift).
 *
 * Layout classes (toggled by vault-custom.js):
 *   .hermes-rc               — base marker (added once)
 *   .hermes-mobile           — <768px viewport (tree=hamburger, graph=bottom-panel)
 *   .hermes-tablet           — 768-1023px (tree=visible, graph=bottom-panel)
 *   .hermes-desktop          — >=1024px (3-panel layout, no overrides)
 *
 * Sidebar state:
 *   .hermes-sidebar-open     — hamburger toggled (mobile only)
 *
 * Strategy: every selector starts with `.vault-app.hermes-rc` to win
 * specificity against obv's `.vault-app` only.
