Google Fonts URL: https://fonts.google.com/share?selection.family=Plus+Jakarta+Sans:ital,wght@0,400;0,500;0,700;1,400. CSS Import: @import url('https://fonts.googleapis.com/css2?family=Plus+Jakarta+Sans:ital,wght@0,400;0,500;0,700;1,400&display=swap');. Tailwind Config: fontFamily: { sans: ['Plus Jakarta Sans', 'sans-serif'] }. Notes: Single-family or System fallback: Plus Jakarta Sans Bold/Medium pairs beautifully with the monochromatic #E0E5EC surface — subtle geometry without competing with the depth effect. Heading: 24–32px Bold (700), letterSpacing -0.5 for modern premium feel. Body: 16px Medium (500), lineHeight 1.4. Caption: 12px Regular (400). Use Text Primary #3D4852 (7.5:1 contrast against #E0E5EC) for all primary text. Use Text Muted #6B7280 (4.6:1 contrast) for secondary text. Accent color #6C63FF only on active labels or focus indicators. Never use italic or thin weights — they lose legibility against the embossed background. System (SF Pro / Roboto) is an acceptable fallback for performance-sensitive implementations..
