## 💼 Portable
Vesper is **fully portable** — zero installation, zero system footprint.
All data lives in a `data/` folder next to the executable:
```
vesper.exe
data/
├── window-state.json ← window position, size, maximized
└── EBWebView/ ← WebView2 data (localStorage, cache)
```
> Nothing is written to AppData, the registry, or any other system location.
> To move Vesper, just copy the exe and optionally the `data/` folder.

## 🧠 Design Philosophy
| | Principle |
|:--|:--|
| 📖 | **Content First** — all UI chrome can be hidden; the reader is the focus |
| 🔤 | **Typography Matters** — Inter at 17px, 1.7 line-height, ~65 char measure |
| 🌙 | **Dark by Default** — deep onyx base `#282C33` reduces eye strain |
| ⌨️ | **Keyboard Driven** — every feature accessible via shortcuts |
| ✨ | **Minimalist Chrome** — the interface gets out of your way |
