## Core Styles

Simplified style tier for quick selection:

| Core Style | Maps To | Best For |
|------------|---------|----------|
| `hand-drawn` | sketch-notes | **Default.** Warm cream paper, black hand-drawn lines, pastel blocks — educational infographics, concept explainers, onboarding, general knowledge articles |
| `vector` | vector-illustration | Knowledge articles, tutorials, tech content |
| `minimal-flat` | notion | General, knowledge sharing, SaaS |
| `sci-fi` | blueprint | AI, frontier tech, system design |
| `editorial` | editorial | Processes, data, journalism |
| `scene` | warm/watercolor | Narratives, emotional, lifestyle |
| `poster` | screen-print | Opinion, editorial, cultural, cinematic |

Use Core Styles for most cases. **When no strong content signal is detected, default to `hand-drawn` (→ sketch-notes).** See full Style Gallery below for granular control.
