In the listening exercise is the phrase "para que la casa esté fresquita."
On the Futuro simple page (https://progress.lawlessspanish.com/revision/glossary/verb-tense-mood/futuro-simple) I couldn't find any page for "estar" in the future tense.
Is "esté" the 1st person singular of estar in futuro simple?
Or does it come from a different word?
