/* ============================================================================
 * nav.css — DEPRECATED.
 *
 * The portal now uses a Shopify-admin-style shell (light left sidebar + slim
 * top bar) built centrally by auth.js and styled by app.css. The old dark
 * top-nav rules that used to live here have been removed.
 *
 * This file is kept as a thin shim so the many `<link rel="stylesheet"
 * href="/nav.css">` tags across the pages don't 404. The only rule left hides
 * any legacy `<header>` scaffold during the brief window before auth.js builds
 * the shell and removes it, preventing a flash of the old markup.
 *
 * New styling belongs in app.css. Do not add rules here.
 * ============================================================================ */
