// Current: PDF.js on main thread with its internal worker
import * as pdfjsLib from "pdfjs-dist";
import pdfWorker from "pdfjs-dist/build/pdf.worker.min.mjs?url";

// PDF.js handles rendering/decoding in its own worker
pdfjsLib.GlobalWorkerOptions.workerSrc = pdfWorker;

// Our parsing logic runs on main thread
export async function extractPdfText(file: File): Promise<string> {
  const buffer = await file.arrayBuffer();
  const pdf = await pdfjsLib.getDocument({ data: buffer }).promise;
  // ... text extraction logic
}
```

Why This Works for Us Now:

- File sizes are small - Typical documents are 1-3 pages (~1.5MB), parsing takes 120-200ms
- Infrequent uploads - Users upload documents intentionally, expect brief processing
- Acceptable UX - brief parsing delays were rarely noticeable on modern devices
- Reduced complexity - No worker lifecycle management, simpler debugging, faster iteration
- PDF.js internal worker - Already handles heavy lifting (rendering, font decoding) off main thread

Measured Performance (Production):
```
Document Size: 1.5MB (3 pages)
Parse Time: 120ms
Minor responsiveness dips: ~100 to 150ms
User perception: Near-instant
