② Length: 2-letter=30 · 3-letter=25 · 4-letter=15 · 5-letter=8
③ Pronounceability (most important): CVCV perfect +20 · no vowels −25 · 4+ consonants −20
④ Meaning: common English word +35 · pinyin-like +18
⑤ Brand fit: AI / e-commerce / finance prefixes
Grades: 💎 Premium ≥ 88 · 🔥 High Value ≥ 72 · ⭐ Great ≥ 58 · 💡 Catchy ≥ 45
