WebAssembly PDF Pipeline
How document streams are manipulated locally inside WebAssembly memory:
// 1. Read binary PDF stream into Uint8Array
const fileBuffer = await file.arrayBuffer();
// 2. Load PDF into local WASM engine
const pdfDoc = await PDFDocument.load(fileBuffer);
// 3. Perform in-memory manipulation and serialize
const outputBytes = await pdfDoc.save();
