/*
 * Atlas dossier tab ownership.
 *
 * This file intentionally loads after atlas-dossier.css. It owns the primary / Life
 * navigation (Station / Life From Here for Rail, Walk Area / Daily Life for Walk),
 * the tab-driven panel split, and the responsive ordering needed to keep that split
 * coherent in the mobile sheet. Keep general card and sheet chrome in their surface
 * owners rather than growing another override layer here.
