# Handoff: Nibiru Docs Design System

## Overview

This handoff covers the **Nibiru documentation site** redesign — a cosmic-themed, dark-primary design system for the framework's docs portal. It includes a complete component library (navigation, code blocks, callouts, tables, API references, search modal, 404, etc.) plus a working full-page preview of the "What is Nibiru?" article styled with the new system.

The metaphor carried throughout: **Nibiru is a star map**. The framework's MMVC architecture (Model · Module · View · Controller) is a constellation, and the docs adopt the same atmospheric vocabulary — deep cosmic plum backgrounds, magenta/cyan/amber accents echoing nebula colors, terminal-aesthetic code blocks, and subtle galaxy textures behind content.

A companion start page (`index-v2.html`) is included for context — it's the marketing site this docs design extends.

## About the Design Files

The files in this bundle are **design references created in HTML** — interactive prototypes showing intended look, behavior, and layout. They are **not production code to copy directly**.

Your task is to **recreate these designs in the Nibiru docs site's actual environment** (likely a static-site generator like Nextra, Mintlify, Docusaurus, or VitePress, given the original screenshot's nav structure), using whatever templating, theming, and component patterns that environment provides. The HTML/JSX in this bundle uses React + Babel inline as a fast prototyping medium — your real implementation should use your stack's idioms.

If no docs framework has been chosen yet, **Nextra (with the docs theme) or Mintlify** are good fits — both support exactly this kind of three-column layout (sidebar + content + on-this-page TOC) with custom theming hooks.

## Fidelity

**High-fidelity.** All colors, typography, spacing, border radii, shadows, and component states are final. Treat the hex values, font sizes, and CSS tokens in `tokens.css` as the source of truth.

The single open question is how dark/light theme switching is wired — the prototype uses a `.theme-light` class on a wrapper element, but your stack may prefer `data-theme` attributes or CSS `color-scheme`.

## Screens / Views

The design canvas in `source/docs-system.html` shows every component grouped into reviewable sections. The full-page preview is the most important reference — it shows how everything composes.

### 1. Full Page Preview ("What is Nibiru?")

**Purpose**: Recreate the documentation article from the original screenshot in the new design system.

**Layout**: Three-column grid, full viewport height.
- **Top nav**: 60px tall, sticky, `backdrop-filter: blur(16px)`, semi-transparent background.

**Structure**: Header (brand + close X) → search button → sidebar (full nav) → footer (Theme / EN / GitHub pills).

## Interactions & Behavior

| Interaction | Trigger | Behavior |
|---|---|---|
| Theme toggle | Click sun/moon icon in nav | Add/remove `.theme-light` on root. Persist to `localStorage`. |
| Sidebar collapse | Click section heading | Toggle children visibility, rotate chevron 90°. Animate `transform: rotate()` 200ms ease. |
| Sidebar active | Current page | Apply `.active` class — magenta gradient bg + 3px magenta glowing left bar. |
| TOC active | Scroll position | Use `IntersectionObserver` on `.prose h2[id]` elements. Highlight matching TOC item. |
| Search open | `⌘K` / `Ctrl+K` / click search button | Open modal, focus input. `Esc` closes. ↑↓ navigates results, ↵ opens. |
| Code copy | Click "Copy" button | Copy to clipboard, swap to "Copied ✓" for 1400ms, then revert. |
| Tab switch | Click trigger | Update `aria-selected`, swap panel. No transition — instant. |
| Card hover | Pointer enter | `transform: translateY(-2px)`, border magenta-tint, arrow fades in & translates. 200ms transitions. |
| Pagination hover | Pointer enter | Chevron translates ±3px in the direction of travel, border magenta. |
| FAB pulse | Always | 2.4s infinite ring animation. |

## State Management

This is a docs site — most state is URL-driven (current page, anchor, search query). The minimum client state needed:

- `theme: "dark" | "light"` (persisted to `localStorage`)
- `sidebarOpen: boolean` (mobile drawer)
- `searchOpen: boolean` (⌘K modal)
- `expandedSections: Record<string, boolean>` (sidebar collapse — defaults to "current section open")
- `activeTocId: string` (driven by IntersectionObserver, not user input)
- `copyStateByBlock: Record<string, boolean>` (per-block "Copied" flash — local component state is fine)

## Design Tokens

All tokens live in **`source/docs-system/tokens.css`**. Copy this file into your codebase verbatim — it's the source of truth.

### Colors (dark theme)
| Name | Hex | Use |
|---|---|---|
| `--space` | `#0b0410` | Page background |
| `--space-2` | `#120822` | Panel surfaces |
| `--space-3` | `#1a0c2e` | Raised surfaces |
| `--plum` | `#2a1545` | Deep accents |
| `--plum-2` | `#3a1d5e` | Hover plum |
| `--star` | `#f4eedb` | Primary text |
| `--star-soft` | `#d8d2c0` | Secondary text |
| `--muted` | `#8b85a3` | Tertiary / labels |
| `--muted-2` | `#5e5878` | Very muted |

| `--nebula-amber` | `#ffb574` | Warning callout / numbers |
| `--nebula-rose` | `#ff7ab8` | Danger callout / keywords |
| `--nebula-green` | `#6ee7b0` | Tip callout / strings |

### Light theme overrides
Defined under `.theme-light` in `tokens.css` — accent colors shift to higher-contrast equivalents (purple replaces magenta, teal replaces cyan) against a parchment `#faf6ec` background.

### Type scale
| Token | px | Use |
|---|---|---|
| `--fs-xs` | 12 | Tiny meta |
| `--fs-sm` | 13 | UI |
| `--fs-base` | 15 | Default |
| `--fs-md` | 16 | Body prose |
| `--fs-lg` | 18 | Page summary |
| `--fs-xl` | 22 | h3 |
| `--fs-2xl` | 28 | h2 |
| `--fs-3xl` | 36 | Page title |
| `--fs-4xl` | 48 | Page hero |

### Spacing
4 / 8 / 12 / 16 / 20 / 24 / 32 / 40 / 48 / 64 — exposed as `--space-1` through `--space-16` (note: var name pun with the cosmic palette `--space`; see comment in tokens.css).

### Radii
4 / 8 / 12 / 16 / 20 / 999px (pill).

### Shadows
- `--shadow-sm`: `0 1px 2px rgba(0,0,0,0.3)`
- `--shadow-md`: `0 8px 24px -8px rgba(0,0,0,0.5)`
- `--shadow-lg`: `0 24px 48px -16px rgba(0,0,0,0.6)`
- `--shadow-glow`: `0 0 24px rgba(184,107,255,0.25)`

### Fonts
- **Sans**: `Inter Tight` (400/500/600/700) — fall back to Inter, system sans
- **Mono**: `JetBrains Mono` (400/500/600)
- No display serif — explicitly all-sans for density and clarity.

Load via Google Fonts:
```html
<link href="https://fonts.googleapis.com/css2?family=Inter+Tight:wght@400;500;600;700&family=JetBrains+Mono:wght@400;500;600&display=swap" rel="stylesheet">
```

Or self-host for performance.

## Assets

- **`source/docs-system/assets/lotus.png`** — The Nibiru lotus mark, cropped from the supplied logo. 861×569. Use at 36px height in the nav (auto width). For a smaller mark icon variant, ask the brand owner for a square crop.
- **`source/docs-system/assets/nibiru-full.png`** — The full logo with "Nibiru" wordmark and "Create, Invent, Impress" tagline. Use on a marketing splash or auth page; not the docs nav.

The docs nav uses **lotus + typeset wordmark separately** so we get crisper text than scaling a PNG, and so the tagline can use our `--muted` token color.

                                     # works offline, just open in a browser)
```

### Where to start

1. Open `preview/nibiru-docs-system.html` in a browser to see the full design canvas. **This file works offline** — everything is inlined, just double-click it.
2. Read `source/docs-system/tokens.css` end-to-end — these tokens drive everything.
3. Read `source/docs-system/components.css` — every visual decision is here, organized by component with `/* ====== COMPONENT ====== */` headers.
4. Check the JSX components for structure (don't port React verbatim — just use them as a reference for DOM hierarchy and class names).
5. Pick a target stack (Nextra / Mintlify / VitePress / your own React app) and start porting. The CSS will land cleanly because it's plain CSS variables + class selectors — no framework lock-in.

### ⚠️ Running the source HTML locally

The files in `source/` use external `<script src="...jsx">` imports. **They will NOT work if you double-click `docs-system.html` directly** — browsers block cross-origin requests on `file://` URLs, so the JSX modules fail to load and you'll see `ReferenceError: TopNav is not defined` in the console.

You need a local HTTP server. From the project root:

```bash
# Python (pre-installed on macOS / Linux)
cd design_handoff_nibiru_docs_system/source
python3 -m http.server 8000
# then open http://localhost:8000/docs-system.html

# OR: Node
npx serve design_handoff_nibiru_docs_system/source
# follow the printed URL

# OR: PHP (since this is a PHP project)
cd design_handoff_nibiru_docs_system/source
php -S localhost:8000
# then open http://localhost:8000/docs-system.html
```

If you just want to **look** at the design without a server, use `preview/nibiru-docs-system.html` — it's a single self-contained file with everything bundled in.

### Migration tips

- **If using Nextra**: Override the theme via `theme.config.tsx` and inject `tokens.css` + `components.css` as global styles. Use Nextra's MDX components (`<Callout>`, `<Tabs>`, etc.) and re-skin them with our class names.
- **If using Mintlify**: Customize via `mint.json` `colors` section + a custom CSS file. Most components in this design map 1:1 to Mintlify primitives.
- **If using VitePress**: Override default theme components in `.vitepress/theme/`. The sidebar/TOC layout maps directly.
- **If rolling your own**: Copy both CSS files into `app/globals.css` (or equivalent), build React/Vue/Svelte components matching the structure in the JSX files, render MDX with a custom component map.

## Open Questions for the Developer

1. **Theme persistence**: How should we remember the user's theme choice? `localStorage` is the prototype's assumption.
2. **Search backend**: The modal is a UI shell — needs a search index. Algolia DocSearch / Mintlify Search / a local index (FlexSearch, Pagefind) all work.
3. **Syntax highlighting**: We define the token classes; you wire them up. Shiki with a custom theme matching our `.tk-*` classes is recommended.
4. **i18n**: The locale dropdown is decorative in the prototype. Wire it up if/when translations exist.
5. **Mobile breakpoints**: Not heavily specified. Suggested: hide right TOC below 1100px, swap left sidebar for the mobile drawer below 768px.
