server.dev.js

/**
 * Local development server for /api/compress and /api/blob-upload.
 * Mirrors the Vercel serverless functions locally.
 *
 * Usage:
 *   node server.dev.js          (port 3001 by default)
 *   PORT=4000 node server.dev.js
 *
 * The Vite dev server proxies /api → http://localhost:3001
 *
 * Note: /api/blob-upload returns { localMode: true } when BLOB_READ_WRITE_TOKEN
 * is not set — the client automatically falls back to legacy multipart upload.
