Preheat oven to 190°C. Line a 23x33 cm (9x13-inch) baking pan with parchment paper, leaving overhang on two sides. Mix graham cracker crumbs, granulated sugar, and melted butter until thoroughly combined. Press mixture evenly into the base of prepared pan. Bake for 10 minutes until lightly golden. Set aside to cool slightly.

In a large mixing bowl, beat softened cream cheese with a hand mixer on medium speed for 2 minutes until smooth and fluffy. Add granulated sugar and blend until fully incorporated. Beat in eggs one at a time. Add sour cream, lemon zest, lemon juice, and vanilla extract, mixing just until smooth. Do not overmix to ensure a light texture.

Pour cheesecake filling evenly over the cooled crust. Tap the pan gently to release any air bubbles.

Dollop small spoonfuls of lemon curd over the cheesecake layer. Using a skewer or toothpick, gently swirl the curd through the filling to create a marbled pattern, avoiding deep cuts into the base.
