+# kami-landing
+
+A drop-in skill that turns a brief into a print-grade kami one-pager —
+warm parchment canvas, ink-blue accent, serif at one weight, no
+italic, no cool grays. The output reads like a white paper or studio
+one-pager, not an app UI.
+
+> **Read first** — the agent contract, schema, and self-check live in
+> [`SKILL.md`](./SKILL.md). This README is the human quick-start.
+
+## What you get
+
+A single self-contained HTML file with:
+
+- **Warm parchment canvas** (`#f5f4ed`), never `#ffffff`.
+- **Single chromatic accent** — ink-blue (`#1B365D`), constrained to
+  ≤ 5% of visible surface.
+- **Serif at weight 500** for hierarchy. No italic anywhere.
+- **Tight print rhythm** — line-heights 1.10–1.55, language-aware
+  letter-spacing.
+- **Tabular-nums** on every numeric stack.
+- **Solid-hex tag fills** (no `rgba()`, which print renderers
+  double-paint).
+- **1px rings + whisper shadows** for depth — no hard drop shadows.
+- **Multilingual** by design (EN / zh-CN / ja stacks selectable via
+  the `language` parameter).
+
+## 30-second tour
+
+The skill is "agent-driven, no script": there's no `compose.ts`. The
+agent reads `SKILL.md`, gathers the brief, then writes
+`out/index.html` directly using the tokens and components catalogued
+in [`design-systems/kami/DESIGN.md`](../../design-systems/kami/DESIGN.md).
+
+To preview the canonical Open Design instance:
+
+```bash
+open example.html
+```
+
+To start a fresh project:
+
+1. Open the skill in your agent (Claude · Cursor · Codex · …).
+2. Answer two rounds of brief questions (identity + content).
+3. Write the file. Done.

+
+## Boundaries
+
+- No external JavaScript. The page is paper, not an app.
+- No hard drop shadows, no neumorphism, no `backdrop-filter`.
+- No second accent color. No italic. No cool blue-grays.
+- One `.tag.brush` per page maximum (it's the only sanctioned gradient).
