Perform Initial Paint Cut-in

What happens here

After an initial coat has been applied to the main wall area (if applicable, ensuring it stayed away from the tape), use a paint brush to precisely apply paint along the edge of the painter's tape. The goal is to create a clean, sharp line against the tape. It is crucial that this "cut-in" paint does not begin to dry before proceeding to the next step, as maintaining a wet edge is key to preventing visible lines.

Goal: Create a sharp paint line against painter's tape using a brush.
