xterm: the terminal holds node-terminal-emulator; its resources through xorg's slot (hq ADR 0208)

It requires x11-display, names itself in TERMINAL, and contributes its X resources
to the xresources slot normal: today's palette and clipboard keys, JetBrainsMono
Nerd Font, 10000 lines of scrollback, all scoped to XTerm* instead of every Xt
program. It owns no file.

The tools are the seat's open, which starts a terminal through the account's
service manager so it outlives the runtime's restarts, and font (in force, what
fontconfig resolves it to, set for new terminals) and colours.
