/*
 * Lead Router — app styles on top of the FPS Design System.
 *
 * The design system (public/vendor/fps-design-system, loaded first) provides the tokens, reset and
 * component classes: .btn, .card, .badge, .input, .table, .callout, .stat-card, .empty-state,
 * .filter-chip, .app-page-header, .avatar. This file only adds the app shell, the login page
 * (spec §12) and a few app-specific pieces.
 *
 * Token contract: semantic tokens only (--color-*, --space-*, --font-*, --border-radius-*). Never
 * --fps-* or --gray-*. Unlayered, so these rules sit above the design system's cascade layers.
