Design Principles

Swiss Design Fundamentals

1. Grid systems - Mathematical layout structure
2. Typography - Clear hierarchy, readable fonts
3. Whitespace - Intentional, functional negative space
4. Objectivity - Content-focused, minimal decoration
5. Asymmetry - Dynamic, purposeful layouts

Typography Scale

/* Perfect Fourth (1.333) */
--text-xs: 0.75rem;    /* 12px */
--text-sm: 0.875rem;   /* 14px */
--text-base: 1rem;     /* 16px */
--text-lg: 1.333rem;   /* 21px */
--text-xl: 1.777rem;   /* 28px */
--text-2xl: 2.369rem;  /* 38px */
--text-3xl: 3.157rem;  /* 50px */

Spacing Scale (8px base)

--space-1: 0.25rem;  /* 4px */
--space-2: 0.5rem;   /* 8px */
--space-3: 0.75rem;  /* 12px */
--space-4: 1rem;     /* 16px */
--space-6: 1.5rem;   /* 24px */
--space-8: 2rem;     /* 32px */
--space-12: 3rem;    /* 48px */
--space-16: 4rem;    /* 64px */

Color System

/* Neutral palette */
--gray-50: #fafafa;
--gray-100: #f4f4f5;
--gray-200: #e4e4e7;
--gray-500: #71717a;
--gray-700: #3f3f46;
--gray-900: #18181b;

/* Accent (customize per project) */
--accent-500: #3b82f6;
--accent-600: #2563eb;
