Generate a cohesive, accessible design system including:
1. A 5-color palette (primary, secondary, accent, background, surface) with HEX and HSL values.
2. Two complementary font pairings (heading and body) available via Google Fonts, with recommended weights.
3. CSS custom properties (variables) for these colors and a base 4px spacing scale (4px, 8px, 16px, 24px, 32px).

Format the output as clean, copy-pasteable CSS code with brief, practical explanations for each choice.
