"""TUI approval labels and modal hints are catalog lookups at render time, not import-time text.

A language pack registered (or ``display.language`` changed) after ``hermes_cli.cli_tui_mixin``
was imported must still reach the approval panel and the hint row; a module-level dict of
English strings would freeze the first language forever.
