✨ Key Architectural Highlights

⚙️ C Core compiled to WASM

The classic Unix utility by Theodore Ts'o compiled with Emscripten into optimized WebAssembly bytecode, executing natively at sub-millisecond speeds.

🧩 ESM & Base64 Inlining

Zero network latency. The WebAssembly binary is encoded directly inside the JavaScript ESM module as a Base64 payload.

🌐 Native Custom Element

Encapsulated within Shadow DOM as <x-pwgen>, offering reactive property binding and framework independence.

💻 Universal Environments

Runs anywhere JavaScript executes: CLI (`npx pwgen`), Node.js CommonJS (`require('pwgen')`), Browser ESM, and PWAs.
