Local preview before checkout
Home, Task and Diff surfaces matter more than a dramatic crop. The studio keeps your image local while you check contrast, panel opacity and restore notes.

Pick the right theme path
The safest conversion path is honest: free local tools first, then paid guidance or human design only when it saves real time.
Use official appearance settings when colors and fonts are enough.
Use a rights-cleared image, crop it around reading zones and keep the recipe declarative.
Order a fixed-scope skin when you need composition, variants and delivery support.
Fastest paid path
The $9.99 pack gives three declarative compositions and practical skin, pet and trust-boundary guides. The $49 service is for one rights-cleared source image and a focused delivery scope.
Trust boundary

Recognizable people, characters, brands and fan concepts are composition references only. Publish or sell themes only with artwork you own or are licensed to use.
