What's Our Typical Salary?
A recruiter working with Kestrel Labs is putting together an offer and asks for one benchmark: the typical salary across the whole company, as a single figure she can quote.
Ten rows is few enough to add up by hand, which is exactly why it is a good place to practise the habit of not doing so. The figure is wanted to two decimal places, because salaries divided by a headcount rarely land on a whole number and a benchmark that silently drops the fraction is a benchmark nobody can reconcile.
employees — one row per employee. salary is the annual figure in whole dollars.

The table already exists in the database — there is nothing to create or load.
Task: Write a query returning a single row with a single column, avg_salary, holding the mean salary across all ten employees, rounded to 2 decimal places.
Example output — shape only. If the mean pay had worked out at ninety-six thousand four hundred and fifty dollars and twenty-five cents, the single row would read:
| avg_salary |
|---|
| 96450.25 |
