Wantedly Style Design System (DESIGN.md, Japanese UI)

Design philosophy: A recruiting SNS with a light, airy feel — brand accent cyan #21bddb placed on pure white whitespace, modernized with Poppins and Helvetica Neue. Follows the Medium / Notion lineage of "SaaS for reading information." - Density: Body text at 14px / line-height 1.57 is slightly Western-leaning and tight. Headings scale up to a 72px hero, giving a high jump ratio between hero and body. - Keywords: Empathy cyan, Poppins modern, pill CTA, translucent text, lightweight whitespace, SNS lightness - Characteristics: - The brand color is #21bddb (cyan / turquoise).
