+replace internal Express server with @push.rocks/smartserve, add PDF→WebP rendering, improve start/stop handling and bump dependencies
+
+- Replace internal Express HTTP implementation with @push.rocks/smartserve and update README wording to reflect HTTP server usage
+- Add PDF→WebP rendering: use pdf.js in-page rendering, capture canvases via Puppeteer to produce WebP buffers; added robust wait/timeout and error handling
+- Add start/stop guards: _isRunning flag, reset readiness Deferred on start, and throw if start called while running
+- Remove direct http/express exports from plugins and stop exporting express; export smartserve from plugins
+- Improve JPEG conversion to produce progressive JPEGs via SmartJimp (sharp mode)
+- Bump dependencies/devDependencies: @push.rocks/smartfs to ^1.5.0, add @push.rocks/smartserve ^2.0.1; devDeps @git.zone/tsbuild ^4.3.0, @git.zone/tstest ^3.3.0, @types/node ^25.3.5

+SmartPDF is your Swiss Army knife for PDF operations in Node.js. Whether you're generating invoices from HTML, snapshotting web pages, merging documents, or converting PDF pages to images — SmartPDF handles it all through a clean, async-first TypeScript API backed by headless Chromium.
+
+### ✨ Features at a Glance
+
+| Feature | Description |
+|---------|-------------|
+| 📝 **HTML → PDF** | Render any HTML string (with full CSS) into an A4-sized PDF |
+| 🌐 **Website → PDF** | Capture a live URL as a PDF — either A4 or full-page scroll |
+| 🔀 **PDF Merging** | Combine multiple PDF buffers into a single document |
+| 🖼️ **PDF → Images** | Convert PDF pages to **PNG**, **WebP**, or progressive **JPEG** |
+| 📑 **Text Extraction** | Pull raw text content from any PDF buffer |
+| 🔌 **Smart Port Management** | Automatic port allocation so multiple instances never collide |
+| 🎛️ **DPI Control** | Built-in scale constants for screen, high-quality, and print resolutions |
+| 🌐 **BYO Browser** | Optionally pass your own Puppeteer `Browser` instance |
+
+## 📦 Installation
+
+```bash
+pnpm add @push.rocks/smartpdf
+```
+
+> **Prerequisites:** SmartPDF uses headless Chromium via Puppeteer under the hood. On most systems this is handled automatically. If you run into browser-launch issues (CI, Docker, etc.), make sure the required system libraries are installed — see the [Puppeteer troubleshooting guide](https://pptr.dev/troubleshooting).
+
+## 🎯 Quick Start
+
+```typescript
+import { SmartPdf } from '@push.rocks/smartpdf';
+import * as fs from 'fs';
+
+// 1. Create and start
+const smartPdf = await SmartPdf.create();
+await smartPdf.start();
+
+// 2. Generate a PDF from HTML
+const pdf = await smartPdf.getA4PdfResultForHtmlString(`
+  <h1>Hello, PDF World! 🌍</h1>
+  <p>Generated with SmartPDF.</p>
+`);
+
+// 3. Write to disk
+fs.writeFileSync('my-first.pdf', pdf.buffer);
+
+// 4. Clean up
+await smartPdf.stop();
+```
+
+Every method returns an `IPdf` object:
+
+```typescript
+interface IPdf {
+  id: string | null;        // Unique identifier
+  name: string;             // Filename
+  buffer: Buffer;           // Raw PDF bytes
+  metadata?: {
+    textExtraction?: string; // Extracted text (when available)
+  };
+}
+```
+
+## 📚 How It Works
+
+SmartPDF spins up a lightweight HTTP server (via `@push.rocks/smartserve`) bound to `localhost` and a headless Chromium browser. When you call a generation method:
+
+1. Your HTML is registered internally and served at `http://localhost:{port}/{id}`
+2. Puppeteer navigates to that URL, waits for the page to fully render, and captures a PDF
+3. A header-based security check ensures only the correct content is captured
+4. The server and browser are torn down when you call `stop()`
+
+This architecture means you get **pixel-perfect CSS rendering**, **web font support**, and **full JavaScript execution** — the same rendering engine that powers Chrome.
+
+## 🏗️ Instance Management
+
+```typescript
+const smartPdf = await SmartPdf.create();
+await smartPdf.start();
+
+// ... your operations ...
+
+await smartPdf.stop();
+```
+
+For production use, wrap in try/finally:
+
+```typescript
+const smartPdf = await SmartPdf.create();
+try {
+  await smartPdf.start();
+  // ... generate PDFs ...
+} finally {
+  await smartPdf.stop();
+}
+```
+
+### 🔌 Smart Port Allocation
+
+Run multiple instances without conflicts:
+
+```typescript
+// Each instance auto-selects a free port (default range: 20000–30000)
+const instance1 = new SmartPdf();
+const instance2 = new SmartPdf();
+await instance1.start(); // e.g. port 20000
+await instance2.start(); // e.g. port 20001
+
+console.log(instance1.serverPort); // 20000
+console.log(instance2.serverPort); // 20001
+
+// Custom range
+const custom = new SmartPdf({ portRangeStart: 4000, portRangeEnd: 5000 });
+
+// Or pin a specific port
+const pinned = new SmartPdf({ port: 3000 });
+```
+
+If a specific port is already in use, `start()` throws an error immediately instead of silently failing.
+
+### 🌐 Bring Your Own Browser
+
+Pass an existing Puppeteer `Browser` instance — SmartPDF won't close it when you call `stop()`:
+
+```typescript
+import puppeteer from 'puppeteer';
+
+const browser = await puppeteer.launch({
+  headless: 'new',
+  args: ['--no-sandbox'],
+});
+
+const smartPdf = await SmartPdf.create();
+await smartPdf.start(browser); // uses your browser
+
+await smartPdf.stop();      // server stops, browser stays open
+await browser.close();       // you manage browser lifecycle
+```
+
+## 🎨 PDF Generation
+
+### 📝 HTML → A4 PDF
+
+Renders at a 794×1122 viewport (A4 at 96 DPI) with full CSS support:
+
+```typescript
+const pdf = await smartPdf.getA4PdfResultForHtmlString(`
+  <style>
+    body { font-family: 'Helvetica', sans-serif; margin: 40px; }
+    .header {
+      background: linear-gradient(135deg, #667eea, #764ba2);
+      color: white; padding: 30px; border-radius: 10px; text-align: center;
+    }
+    table { width: 100%; border-collapse: collapse; margin-top: 20px; }
+    th, td { border: 1px solid #ddd; padding: 8px; text-align: left; }
+    th { background: #f5f5f5; }
+  </style>
+
+  <div class="header">
+    <h1>Invoice #2024-001</h1>
+  </div>
+
+  <table>
+    <tr><th>Item</th><th>Qty</th><th>Price</th></tr>
+    <tr><td>Widget Pro</td><td>5</td><td>$49.99</td></tr>
+    <tr><td>Gizmo Ultra</td><td>2</td><td>$129.99</td></tr>
+  </table>
+`);
+
+fs.writeFileSync('invoice.pdf', pdf.buffer);
+```
+
+### 🌐 Website → PDF
+
+Two methods depending on your needs:
+
+```typescript
+// Standard capture — uses the document's own dimensions
+const pdf = await smartPdf.getPdfResultForWebsite('https://example.com');
+
+// Full-page capture — scrolls to bottom, captures everything as a single page
+const fullPdf = await smartPdf.getFullWebsiteAsSinglePdf('https://example.com');
+```
+
+`getPdfResultForWebsite` uses a 1980×1200 viewport and respects the page's own width/height. `getFullWebsiteAsSinglePdf` uses a 1920px-wide viewport and measures the full scroll height, producing a single tall page.
+
+### 🔀 Merge Multiple PDFs
+
+Combine any number of PDF buffers into one document using `pdf-lib`:
+
+```typescript
+const invoice = await smartPdf.readFileToPdfObject('./invoice.pdf');
+const terms = await smartPdf.readFileToPdfObject('./terms.pdf');
+const appendix = await smartPdf.getA4PdfResultForHtmlString('<h1>Appendix</h1>...');
+
+const merged = await smartPdf.mergePdfs([
+  invoice.buffer,
+  terms.buffer,
+  appendix.buffer,
+]);
+
+fs.writeFileSync('complete-package.pdf', merged);
+```
+
+### 📑 Read a PDF from Disk
+
+```typescript
+const pdfObject = await smartPdf.readFileToPdfObject('./document.pdf');
+console.log(pdfObject.name);   // "document.pdf"
+console.log(pdfObject.buffer); // <Buffer ...>
+```
+
+### 📖 Extract Text
+
+Pull raw text from any PDF buffer:
+
+```typescript
+const text = await smartPdf.extractTextFromPdfBuffer(pdf.buffer);
+console.log(text);
+```
+
+> Uses [pdf2json](https://github.com/modesty/pdf2json) under the hood. Works best with text-based PDFs; scanned documents may return limited results.
+
+## 🖼️ PDF → Image Conversion
+
+Convert PDF pages to raster images using Puppeteer + PDF.js. Each page becomes a separate image buffer.
+
+### PNG — Lossless Quality
+
+```typescript
+const pngPages = await smartPdf.convertPDFToPngBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH, // 3.0 = ~216 DPI (default)
+});
+
+pngPages.forEach((png, i) => {
+  fs.writeFileSync(`page-${i + 1}.png`, Buffer.from(png));
+});
+```
+
+### WebP — Modern & Efficient
+
+25–60% smaller than PNG at similar visual quality:
+
+```typescript
+const webpPages = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
+  scale: 2.0,     // ~144 DPI
+  quality: 90,    // 0–100 (default: 85)
+});
+```
+
+### JPEG — Progressive Loading
+
+Generates true progressive JPEGs (multi-pass rendering) via sharp:
+
+```typescript
+const jpegPages = await smartPdf.convertPDFToJpegBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH,
+  quality: 85,       // 0–100 (default: 85)
+  maxWidth: 1920,    // optional dimension constraints
+  maxHeight: 1080,
+});
+```
+
+### 📏 DPI & Scale Reference
+
+All image methods accept a `scale` parameter. PDF.js renders at 72 DPI by default, so `scale` is a multiplier:
+
+| Constant | Value | DPI | Use Case |
+|----------|-------|-----|----------|
+| `SmartPdf.SCALE_SCREEN` | 2.0 | ~144 | Web display, thumbnails |
+| `SmartPdf.SCALE_HIGH` | 3.0 | ~216 | General purpose (default) |
+| `SmartPdf.SCALE_PRINT` | 6.0 | ~432 | Print-quality output |
+
+Or calculate a custom scale:
+
+```typescript
+const scale = SmartPdf.getScaleForDPI(300); // → 4.167
+```
+
+### 🖼️ Dimension Constraints
+
+All image methods support `maxWidth` and `maxHeight` to cap output size while preserving aspect ratio:
+
+```typescript
+// High-res render, but capped at 800×1000 px
+const constrained = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH,
+  quality: 90,
+  maxWidth: 800,
+  maxHeight: 1000,
+});
+```
+
+### 📊 Format Comparison
+
+| Format | Typical Size vs PNG | Lossy? | Transparency | Progressive | Best For |
+|--------|-------------------|--------|--------------|-------------|----------|
+| **PNG** | baseline | No | ✅ | — | Screenshots, diagrams, text-heavy docs |
+| **WebP** | 40–75% | Yes | ✅ | — | Modern web apps, thumbnails |
+| **JPEG** | 50–70% | Yes | ❌ | ✅ | Photos, complex graphics, email |
+
+## ⚡ Parallel Processing
+
+Process multiple URLs concurrently with separate instances:
+
+```typescript
+const urls = [
+  'https://example.com/page1',
+  'https://example.com/page2',
+  'https://example.com/page3',
+];
+
+// Spin up parallel instances
+const instances = await Promise.all(
+  urls.map(() => SmartPdf.create())
+);
+await Promise.all(instances.map(i => i.start()));
+
+// Generate in parallel
+const pdfs = await Promise.all(
+  urls.map((url, i) => instances[i].getFullWebsiteAsSinglePdf(url))
+);
+
+// Merge all results
+const merged = await instances[0].mergePdfs(pdfs.map(p => p.buffer));
+fs.writeFileSync('all-pages.pdf', merged);
+
+// Clean up
+await Promise.all(instances.map(i => i.stop()));
+```
