/**
 * Evident ICU Footer Foundation
 *
 * Purpose:
 * Consolidate the public footer into one coherent system:
 * - compact route map
 * - centered brand block
 * - entity/contact/start/notice disclosure grid
 * - bottom status/newsletter bar
 *
 * This file is loaded after legacy footer CSS and should become the migration
 * target for the shared @evident-technologies/layout-foundation footer pattern.
