Deflect aesthetic tweaks during the vision phase
Decision. During the vision phase, aesthetic change requests are acknowledged, filed as decision records with a resolve-by tier, and not acted on — unless semantic (a screen needs a danger state; a layout misrepresents the feature). Preset themes absorb the itch: switching costumes is free, tailoring one is filed.
Why. The gradient mines are where product dreaming goes to die. The marketing shell is a fixed boring template on purpose; the only variables are product content and screenshots.
