/*
 * M1 Limousine Design System
 * Release: 2026.09.01.13 / m1limo-20260901-adaptive-operations-workbench.1
 *
 * Principles:
 * - Quiet, high-contrast enterprise surfaces instead of decorative gradients.
 * - Semantic alias tokens; no page should need to know raw palette values.
 * - 4px-based spacing, consistent 40/44px controls, clear focus states.
 * - Responsive reflow down to 320px without horizontal page scrolling.
 * - Legacy primitives load first; the modern foundation/shell/auth layers then
 *   establish the product system; page modules may finally specialize layout.
 * - Page-specific CSS is intentionally placed in the `page` layer and must
 *   outrank generic foundation rules so spacing and page geometry are stable.
