"""Every event_type in EVENT_VARIABLES needs a matching SAMPLE_DATA entry.
Regression: location_ha_sensor_alert (#2824) was added to EVENT_VARIABLES but
never given a SAMPLE_DATA entry. The template preview endpoint falls back to
an empty sample dict for an event type it has no data for, so every
{placeholder} in the template silently disappears — "{location}: {sensor} is
{state}" rendered as just ": is " with nothing to say what did what.
