> 📟 is-legacy-terminal
Detect whether the terminal is legacy.
Checks if terminal is legacy (limited rendering, flicker-prone on rapid redraws, etc.). On Windows, returns True if CMD or PowerShell ISE not hosted in modern shell. On *nix systems, returns True if env.TERM is 'dumb' or 'unknown' (indicating a very basic terminal).

🔌 API usage
import is_legacy_terminal
if is_legacy_terminal():
print('Is legacy terminal!')
else:
print('Is modern terminal!')
Note: Most type checkers will falsely warn is_legacy_terminal is not a callable module because they are incapable of analyzing runtime behavior (where the module is replaced w/ a function for cleaner, direct access). You can safely suppress such warnings using # type: ignore.
