# Presentation Generator

## Overview

Create stunning presentations in neobrutalism style with Agency brand colors. Generate interactive HTML presentations with smooth scrolling navigation, export individual slides as PNG, or create PDF documents.

**Output formats:**
- **HTML** - Interactive presentation with navigation dots, keyboard support, smooth scrolling
- **PNG** - Individual slide images via Playwright (1920x1080)
- **PDF** - Multi-page document via Playwright

## Quick Start

### 1. Create presentation from JSON/YAML content

```bash
node scripts/generate-presentation.js --input content.json --output presentation.html
```

### 2. Export to PNG slides

```bash
node scripts/export-slides.js presentation.html --format png --output ./slides/
```

### 3. Export to PDF

```bash
node scripts/export-slides.js presentation.html --format pdf --output presentation.pdf
```

## Brand Integration

This skill references `brand-agency` for consistent styling:

          └─────┘  ╚═════╝  ┗━━━━━┛

Lines:    ─ │ ═ ║ ━ ┃ ━━━ ───

Arrows:   → ← ↑ ↓ ▶ ◀ ▲ ▼

Shapes:   ● ○ ■ □ ▲ △ ★ ☆ ◆ ◇

Blocks:   █ ▓ ▒ ░
```

## Dependencies

- Node.js 18+
- Playwright (`npm install playwright`)

## Tips

1. **Use ASCII sparingly** - Great for tech/dev presentations, can feel dated otherwise
2. **Stick to brand colors** - Don't mix custom colors, use the 5-color palette
3. **Big text on title slides** - h1 should be 4-5rem minimum
4. **One idea per slide** - Neobrutalism works best with focused content
5. **Test interactivity** - Always preview HTML before exporting
