## Description

ToaruOS is an independent operating system built from the ground up without external dependencies. It features a custom x86-64 kernel that supports symmetric multiprocessing and paging, paired with a graphical windowing system and a dedicated bytecode interpreter for application logic.

The system distinguishes itself by integrating an embedded Python environment for system-level development and a custom graphical interface that handles its own window composition and text rendering. It includes a compatibility layer for third-party application support and a system package manager for handling pre-compiled binaries.

The broader capability surface encompasses a full network stack capable of TCP server hosting, a dynamic binary loader for resolving symbols at runtime, and a suite of user-space tools including a syntax-highlighting text editor and a tabbed terminal emulator.
