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.
