Cinnamon Focaccia

I got this recipe from Chatgpt, but I added butter and sugar to the dough. It's similar to a recipe by Amy Bakes Bread. This version is a halved recipe of those two.

 For the dough:

• 250g bread flour

• 50g active sourdough starter (at 100% hydration)

• 175g water

• 5g salt

• 10g sugar

• 20g unsalted butter

For the cinnamon swirl:

• 35g brown sugar

• 2.5g ground cinnamon

• unsalted butter

• grated nutmeg

• orange zest
