/**
 * Nordic Design System
 * Scandinavian-inspired minimal warmth.
 *
 * Principles:
 * - Warm whites and soft grays (never pure white or black)
 * - Muted earth tones as accents (sage, clay, stone)
 * - Generous border-radius for organic feel
 * - Abundant whitespace — let content breathe
 * - Accessible system sans-serif stack
 * - Subtle, warm shadows
 * - Calm and inviting, never cold
