TTUL browser Linux
==================
Cloudflare serves these static assets. v86 translates the guest's x86
instructions into WebAssembly inside your browser. There is no server-side
VM and no SSH connection to an external host. xterm.js connects to the
guest's serial console. Each tab has its own machine and localhost network.

The 2005 mailbox and websites are authored fiction, not recovered archives.
The programs are real: Alpine Linux, Bash, Mutt, Lynx, nano, BusyBox, p4 and
p4d. The clock starts on November 9, 2005. Most kernel and binary versions are newer. uname and distro release files
wear a fictional Debian 3.1 sarge / Linux 2.6.12 identity. Use
/bin/busybox uname -a for the actual kernel; original distribution files
are in /usr/share/ttul/runtime. Git is the real July 2005 version 0.99.
There is no Internet network adapter, external email delivery or telemetry.

Save session writes an entire VM snapshot and terminal screen to IndexedDB.
Restore uses that snapshot when it matches the current guest image. Browser
storage can be cleared or evicted, so don't keep anything irreplaceable here.
