Font Stack (preferred):

font-family: Inter, system-ui, -apple-system, BlinkMacSystemFont,
             "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell,
             "Open Sans", "Helvetica Neue", sans-serif;

CJK Text (Chinese, Japanese, Korean):

font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei",
             "Noto Sans CJK SC", sans-serif;

Logo Wordmark Style:

• Lowercase with open contours and rounded edges
• Slightly detached triangular segment in the letter "K"
• Not available for public use — refer to official brand assets

Typography Rules:

• Maintain generous letter-spacing for headings
• Use regular weight (400) for body text, medium (500) or semibold (600) for headings
• Avoid using thin (100/200) weights for body text
• Left-align text by default for readability

Logo

• Emblem: A friendly blue whale mascot — symbolizing wisdom, depth, exploration, and calm
• Wordmark: Lowercase "deepseek" in a rounded geometric sans-serif with open contours
• The whale complements the name's implication of "deep" exploration
• Always use the official logo assets; do not recreate, modify, or distort
• Maintain clear space around the logo equal to at least the height of the "d" in "deepseek"
