# Design System — Red Team Operations Map

Reusable design spec extracted from `kypvas.github.io/red-team-map/`. Dark "operator briefing / terminal" aesthetic: information-dense, color-coded taxonomy, monospace-first, zero ornament.

---

## 1. Philosophy

- **Dark, flat, terminal-inspired.** No gradients, no drop shadows, no glows. Depth comes from 1px borders on slightly lighter card backgrounds.
- **Information over decoration.** Every visual element serves data density — cards, tags, colored borders, inline code.
- **Color as taxonomy.** 10 accent hues are not decoration — each one *means* a category (red = evasion/payload, cyan = lateral, purple = C2, etc.). Reuse hues consistently across projects so color carries meaning.
- **Monospace as identity.** `JetBrains Mono` for everything structural (titles, labels, code, tags). `IBM Plex Sans` only for prose body.
- **Comment-style section markers.** Headings begin with `//` — carries the "source code / operator notes" metaphor.

---

## 2. Color Tokens

All colors are declared as CSS custom properties on `:root`. Copy-paste verbatim:

```css
:root {
  /* Surfaces */
  --bg:          #0a0e1a;  /* page background — deep navy-black */
  --bg-card:     #111827;  /* card / panel background */
  --border:      #1e2d3d;  /* default 1px border, separators */

  /* Text */
  --text:        #94a3b8;  /* default body copy (slate) */
  --text-bright: #f8fafc;  /* titles, emphasis */
  --text-dim:    #64748b;  /* metadata, subtitles, arrow labels */
  /* #475569 used inline for code comments */

  /* Accent palette — each one maps to a category */
  --red:    #ef4444;  /* evasion, payload, privesc, danger */
  --orange: #f59e0b;  /* access, credentials, AD, MOTW */
  --yellow: #eab308;  /* exfil */
  --green:  #10b981;  /* phishing, social */
  --cyan:   #06b6d4;  /* lateral movement, default code highlight */
  --blue:   #3b82f6;  /* infrastructure, cloud */
  --purple: #8b5cf6;  /* C2, macOS, tooling */
  --pink:   #ec4899;  /* injection */
  --rose:   #f43f5e;  /* OPSEC, vishing */
  --teal:   #14b8a6;  /* persistence, linux */
}
```

### Usage pattern — tinted fills

Never use accent color as a solid background. Always as `rgba(accent, 0.10–0.15)` behind solid-colored text:

```css
.tag.c2   { background: rgba(139, 92, 246, 0.15); color: var(--purple); }
.tag.cred { background: rgba(245, 158, 11, 0.15); color: var(--orange); }
code      { background: rgba(6, 182, 212, 0.08); color: var(--cyan); }
code.vuln { background: rgba(239, 68, 68, 0.10); color: var(--red); }
code.tool { background: rgba(139, 92, 246, 0.10); color: var(--purple); }
```

---

## 3. Typography

### Font stack

```html
<link href="https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@300;400;500;600;700&family=IBM+Plex+Sans:wght@300;400;500;600&display=swap" rel="stylesheet">
```

- **`JetBrains Mono`** — headings, labels, code, tags, navigation, anything structural.
- **`IBM Plex Sans`** — prose body only (`<p>`, card descriptions).
- Weights used: Mono `300 / 400 / 500 / 600 / 700`, Plex Sans `300 / 400 / 500 / 600`.

### Scale

| Role            | Family          | Size | Weight | Extras                          |
|-----------------|-----------------|------|--------|---------------------------------|
| Page title (h1) | JetBrains Mono  | 28px | 700    | `letter-spacing: -0.5px`        |
| Subtitle        | JetBrains Mono  | 14px | 300    | color `--text-dim`              |
| Section (h2)    | JetBrains Mono  | 18px | 600    | `border-bottom: 1px var(--border)`, `padding-bottom: 12px` |
| Card title (h3) | JetBrains Mono  | 14px | 600    | color `--text-bright`           |
| Card sub-label  | JetBrains Mono  | 10px | 400    | `letter-spacing: 0.5px`, `--text-dim` |
| Section desc    | JetBrains Mono  | 12px | 400    | `--text-dim`                    |
| Body copy       | IBM Plex Sans   | 12px | 400    | `line-height: 1.7`              |
| Flow node       | JetBrains Mono  | 10px | 400    |                                 |
| Arrow label     | JetBrains Mono  | 8px  | 400    | `--text-dim`                    |
| Tag / pill      | JetBrains Mono  | 9px  | 600    | `text-transform: uppercase; letter-spacing: 1px` |
| Inline code     | JetBrains Mono  | 10px | 400    |                                 |
| `<pre>` block   | JetBrains Mono  | 11px | 400    | `line-height: 1.7`              |
| Footer          | JetBrains Mono  | 11px | 400    | `--text-dim`                    |

### Global body

```css
body {
  background: var(--bg);
  color: var(--text);
  font-family: 'IBM Plex Sans', sans-serif;
  padding: 40px 60px;
  line-height: 1.6;
}
```

---

## 4. Layout & Spacing

- **Container**: `max-width: 1400px; margin: 0 auto;`
- **Page padding**: `40px 60px` (desktop-first, no mobile breakpoints in the source)
- **Grid** for card collections:
  ```css
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(420px, 1fr));
  gap: 16px;
  ```
- **Section rhythm**: `margin-top: 60px; margin-bottom: 30px` on section headers.
- **Separators**: thin hairlines only — `border-top: 1px solid var(--border); margin: 40px 0`.
- **Line-height**: 1.6 globally, 1.7 inside cards and `<pre>` blocks for dense technical content.

---

## 5. Components

### 5.1 Header / Hero

```html
<header>
  <h1>Red Team <span>Operations</span> <span class="acc2">Architecture</span> Map v1.1</h1>
  <div class="subtitle">Comprehensive Operator Reference — From Infrastructure to Impact</div>
</header>
```

```css
header        { text-align: center; margin-bottom: 50px; }
header h1     { font: 700 28px 'JetBrains Mono'; color: var(--text-bright); letter-spacing: -0.5px; margin-bottom: 8px; }
header h1 span         { color: var(--red); }
header h1 .acc2        { color: var(--purple); }
header .subtitle       { font: 300 14px 'JetBrains Mono'; color: var(--text-dim); }
```

> **Pattern**: white title with two coloured accent words (red + purple). Reuse `<span>` to highlight 1–2 keywords only.

### 5.2 Section heading

```html
<div class="section-header">
  <h2><span>//</span> Operation <span class="red">Flow Chains</span></h2>
  <p class="section-desc">End-to-end attack chains ...</p>
</div>
```

```css
.section-header          { margin-top: 60px; margin-bottom: 30px; }
.section-header h2       { font: 600 18px 'JetBrains Mono'; color: var(--text-bright);
                           padding-bottom: 12px; border-bottom: 1px solid var(--border); }
.section-header h2 span  { color: var(--cyan); }            /* the "//" marker */
.section-header h2 .red  { color: var(--red); }              /* + .green / .orange / .purple / .pink / .teal / .yellow / .blue */
.section-desc            { font: 12px 'JetBrains Mono'; color: var(--text-dim); margin-top: 8px; }
```

> **Signature move**: every h2 starts with a cyan `//` followed by a plain word and one colored word — source-code comment vibe.

### 5.3 Detail card

```css
.detail-card {
  background: var(--bg-card);
  border: 1px solid var(--border);
  border-radius: 10px;
  padding: 20px;
}
.detail-card h3        { font: 600 14px 'JetBrains Mono'; color: var(--text-bright); margin-bottom: 4px; }
.detail-card .card-sub { font: 10px 'JetBrains Mono'; color: var(--text-dim); margin-bottom: 12px; letter-spacing: 0.5px; }
.detail-card .card-body { font-size: 12px; line-height: 1.7; }

/* accent-border variants */
.border-red   { border-color: var(--red)    !important; }
.border-cyan  { border-color: var(--cyan)   !important; }
/* ... one class per accent */
```

> Cards share identical chrome; they are **distinguished solely by border color**. That single accent ties card → category → tag → flow-node without repeating the hue anywhere else.

### 5.4 Tag / pill

```css
.tag {
  font: 600 9px 'JetBrains Mono';
  text-transform: uppercase;
  letter-spacing: 1px;
  padding: 3px 8px;
  border-radius: 4px;
  display: inline-block;
  margin-bottom: 8px;
  margin-right: 4px;
}
.tag.c2       { background: rgba(139, 92, 246, 0.15); color: var(--purple); }
.tag.evasion  { background: rgba(239, 68, 68,  0.15); color: var(--red); }
.tag.lateral  { background: rgba(6,   182, 212, 0.15); color: var(--cyan); }
/* ... one class per category */
```

### 5.5 Flow node + arrow

Nodes chain horizontally in a `flex` row with thin SVG arrows between them.

```css
.flow-block { margin-bottom: 18px; }
.flow-title { font: 600 12px 'JetBrains Mono'; margin-bottom: 10px; }
.flow-title.red    { color: var(--red); }     /* one per accent */

.flow-row   { display: flex; align-items: center; gap: 4px; flex-wrap: wrap; padding: 10px 0; }

.flow-node {
  background: var(--bg-card);
  border: 1px solid var(--border);
  border-radius: 6px;
  padding: 8px 12px;
  font: 10px 'JetBrains Mono';
  color: var(--text);
  white-space: nowrap;
  flex-shrink: 0;
}
.flow-node.hl-red    { border-color: var(--red);    color: var(--red); }
.flow-node.hl-cyan   { border-color: var(--cyan);   color: var(--cyan); }
/* ... one per accent */

.flow-arrow              { display: flex; flex-direction: column; align-items: center; flex-shrink: 0; }
.flow-arrow svg          { width: 36px; height: 20px; }
.flow-arrow .arrow-label { font: 8px 'JetBrains Mono'; color: var(--text-dim); margin-top: -2px; }
```

Arrow SVG template (inline, stroke colour = destination-node accent):

```html
<svg viewBox="0 0 36 20">
  <line x1="0" y1="10" x2="31" y2="10"
        stroke="#10b981" stroke-width="1.5"
        marker-end="url(#arrowG)"/>
</svg>
```

### 5.6 Data-flow / code card

```css
.data-flow-card {
  background: var(--bg-card);
  border: 1px solid var(--border);
  border-radius: 10px;
  padding: 24px;
  margin-bottom: 20px;
}
.data-flow-card h4   { font: 600 13px 'JetBrains Mono'; color: var(--text-bright); margin-bottom: 12px; }
.data-flow-card pre  { font: 11px 'JetBrains Mono'; line-height: 1.7; color: var(--text-dim); overflow-x: auto; }
.data-flow-card pre .key     { color: var(--cyan);   font-weight: 600; }
.data-flow-card pre .val     { color: var(--text-bright); }
.data-flow-card pre .type    { color: var(--blue); }
.data-flow-card pre .comment { color: #475569; font-style: italic; }
.data-flow-card pre .danger  { color: var(--red);    font-weight: 600; }
```

> Pseudo-syntax-highlighting via `<span class="key|val|type|comment|danger">` inside `<pre>` blocks — mimics an IDE theme without a real parser.

### 5.7 Inline code

```css
code               { font: 10px 'JetBrains Mono'; padding: 2px 6px; border-radius: 3px;
                     background: rgba(6, 182, 212, 0.08); color: var(--cyan); }
code.vuln          { background: rgba(239, 68, 68,  0.10); color: var(--red); }
code.tool          { background: rgba(139, 92, 246, 0.10); color: var(--purple); }
```

### 5.8 List inside card

```css
.card-list          { list-style: none; padding: 0; }
.card-list li       { padding: 3px 0; border-bottom: 1px solid rgba(255, 255, 255, 0.03); }
```

> Near-invisible divider (`rgba(255,255,255,0.03)`) — rhythm without visual noise.

### 5.9 Footer

```css
footer {
  text-align: center;
  margin-top: 60px;
  padding: 30px 0;
  border-top: 1px solid var(--border);
  font: 11px 'JetBrains Mono';
  color: var(--text-dim);
}
```

## 6. Borders, Radii, Elevation

| Element        | Radius | Border                       |
|----------------|--------|------------------------------|
| Detail card    | 10px   | 1px solid var(--border) or accent |
| Data-flow card | 10px   | 1px solid var(--border)      |
| Flow node      | 6px    | 1px solid var(--border) or accent |
| Tag            | 4px    | none                         |
| Inline code    | 3px    | none                         |

- **No `box-shadow` anywhere.**
- **No gradients.** Surfaces are flat hex fills.
- **Depth cue** = border on a `#111827` panel over a `#0a0e1a` background. That's the whole elevation system.

---

## 7. Motion

The stylesheet defines **no transitions, no hovers, no animations**. Static document. If you add motion in derivative work, keep it restrained: ~120 ms fades on border-color at most. Don't introduce scale, shadow, or glow effects — they'd break the briefing aesthetic.

---

## 8. Iconography

No icon font, no Lucide/Heroicons. All pictograms are **inline SVG arrows** with `stroke-width: 1.5` and `<marker-end>` arrowheads, one per accent color. Tags replace icons: `[C2]`, `[EVASION]`, `[LATERAL]` carry the same recognition load.

If icons are ever added, use a thin (1.5px) monochrome line set (e.g. Lucide `strokeWidth={1.5}`) and color them with accent vars.

---

## 9. Reusable Starter Template

Drop-in `<head>` + body baseline for a new project in this style:

```html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Project Name</title>
  <link href="https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@300;400;500;600;700&family=IBM+Plex+Sans:wght@300;400;500;600&display=swap" rel="stylesheet">
  <style>
    :root {
      --bg: #0a0e1a; --bg-card: #111827; --border: #1e2d3d;
      --text: #94a3b8; --text-bright: #f8fafc; --text-dim: #64748b;
      --red:#ef4444; --orange:#f59e0b; --yellow:#eab308; --green:#10b981;
      --cyan:#06b6d4; --blue:#3b82f6; --purple:#8b5cf6; --pink:#ec4899;
      --rose:#f43f5e; --teal:#14b8a6;
    }
    * { margin: 0; padding: 0; box-sizing: border-box; }
    body { background: var(--bg); color: var(--text); font-family: 'IBM Plex Sans', sans-serif; padding: 40px 60px; line-height: 1.6; }
    .container { max-width: 1400px; margin: 0 auto; }
  </style>
</head>
<body>
  <div class="container">
    <header>
      <h1>Project <span style="color:var(--red)">Name</span> <span style="color:var(--purple)">Subtitle</span></h1>
      <div class="subtitle">One-line mission statement</div>
    </header>
    <!-- sections with <h2>// Section <span class="red">Name</span></h2> ... -->
  </div>
</body>
</html>
```
