"""Shared verbose flag for user-facing prints.
Defaults off. Toggle via `set_verbose(True)` (e.g. from run_gradio.py --verbose)
or by setting the environment variable `SAT_VERBOSE=1`.
Warnings and errors should continue to use plain `print()` — `vprint()` is only
for informational/progress messages that are noisy at default verbosity.
