"""
Sensor KPI summary card (text-only)
===================================

A label-and-value summary tile rendered with ``axis("off")`` and
``ax.text``. Useful as a building block for dashboards where a compact
numeric snapshot sits alongside charts.

dartwork-mpl's relative typography (``dm.fs(n)``) is used so that the
tile rescales cleanly with the surrounding preset.
