Minimal Digital Timer Phone Case Sticker Prompts

Create a clean, high-contrast vector illustration of a minimal digital timer displayed on a smartphone screen. The design should feature sharp lines, no shading or gradients, and a pure white background, ideal for die-cut sticker printing. The timer display includes a rectangular screen with bold, simple numerals showing [TIME_PLACEHOLDER], along with minimalistic control icons or buttons. Ensure the illustration is easily recognizable, with a modern and sleek aesthetic, perfect for high-quality sticker production.
