kami-landing

Produce a single-page document in the kami (紙 / 纸) design system. The aesthetic borrows from editorial print, technical white papers, and old typewritten correspondence — the goal is good content on good paper, not modern app UI.

Design system source of truth: design-systems/kami/DESIGN.md. Read it before shipping. Tokens, type rules, the "ten invariants", and forbidden colors all live there.

What you get

A single self-contained HTML file with:

• Warm parchment canvas (#f5f4ed) — never #ffffff.
• Single chromatic accent — ink-blue (#1B365D), used on the section number, the headline accent word, the left rule of the manifesto, and the metric values. Anywhere else, ink-blue must cover ≤ 5% of the document surface area.
• Serif at one weight (500) for hierarchy — Charter (EN), TsangerJinKai02 / Source Han Serif (CN), or YuMincho (JA), selected by the language parameter. No italic anywhere.
• Tight print rhythm — line-heights 1.10–1.55, letter-spacing per language (0 for EN, 0.35px for CN, 0.02em for JA).
• Numeric stacks set in font-variant-numeric: tabular-nums so metric columns and pagination digits sit cleanly aligned.
• Depth via 1px rings + whisper shadows (0 4px 24px rgba(0,0,0,0.05)). No hard drop shadows, no neumorphism, no backdrop-filter blurs.
• Tag fills as solid hex (e.g. #E4ECF5), never rgba() — print renderers double-paint alpha tags.
• Responsive at 1280 / 980 / 768 / 560.
