  WASI-Env is a portable, single-file HTML WebAssembly execution harness 
  and POSIX terminal running locally with zero external dependencies.

  Features:
  - 90 C WASM Binaries compiled from Suckless sbase and ubase
  - 46+ wasi_snapshot_preview1 syscalls intercepted
  - Official SQLite3 C amalgamation embedded
  - Dynamic /proc VFS and POSIX termios (RAW mode)
  - In-browser C compiler (/bin/cc) generating WASM on demand
  - Persistent IndexedDB storage supporting upstream /bin/df

  Note:
  This is a messy work-in-progress prototype with many artifacts. I used 
  an earlier build of this environment as the base to isolate and create 
  a standalone 6MB single-file Doom port: https://wasi-doom.netlify.app/

  The entire single file fits in an LLM context window—feel free to 
  inspect the Colab, untangle the pieces, and hack on it.
