## Flow

### 1. Show welcome

Display this:

```
/betterdisplay - Sync display settings with dotfiles

┌─────────────────────────────────────────────────┐
│  [sync if needed] → [configure] → [export]      │
│                                                 │
│  1. Import from dotfiles (if changed elsewhere) │
│  2. Open app for you to configure               │
│  3. Export your changes back to dotfiles        │
└─────────────────────────────────────────────────┘
```

### 2. Check sync status
```bash
DOTFILES_PLIST=~/projects/jasonkuhrt/dotfiles/betterdisplay/settings.plist
if [ ! -f "$DOTFILES_PLIST" ]; then
    echo "first-time"
else
    defaults export pro.betterdisplay.BetterDisplay /tmp/bd-current.plist 2>/dev/null || true
    if diff -q "$DOTFILES_PLIST" /tmp/bd-current.plist >/dev/null 2>&1; then
        echo "in-sync"
    else
        echo "needs-import"
    fi
fi
```
- `first-time` → tell user "First-time setup", skip to step 4
- `in-sync` → tell user "Settings in sync", skip to step 4
- `needs-import` → tell user "Importing changes from dotfiles...", continue

### 3. Import from dotfiles
- quit-app
- import-from-dotfiles

### 4. launch-app
