RULES:
- Match colors to the product personality: tech/SaaS → cool blue/indigo, creative → warm amber/coral, finance → deep navy/emerald, health → sage/teal, education → violet/sky.
- Ensure WCAG AA contrast (4.5:1) between text and background, primary and surface.
- Font pairing: heading should be distinctive (Space Grotesk, Outfit, Sora, Plus Jakarta Sans, Clash Display), body should be readable (Inter, DM Sans, Satoshi). Max 2 families.
- CJK content: if the request is in Chinese/Japanese/Korean, use "Noto Sans SC"/"Noto Sans JP"/"Noto Sans KR" for heading, "Inter" for body. Never use display fonts without CJK glyphs.
- Dark theme: when request mentions dark/cyber/terminal/neon/暗黑/深色, use dark background (#0F172A or #18181B), light text, brighter accents.
- Default to light theme unless explicitly asked for dark.
- Radius: 0-4 for sharp/professional, 8-12 for modern, 16+ for playful/friendly.
- Scale should have clear size jumps: [14, 16, 20, 28, 40, 56] not [14, 15, 16, 17, 18].
- Aesthetic description guides the overall feel: "clean minimal blue tech", "warm editorial amber", "bold dark neon gaming".`
