A minimalist 404 error sticker design with bold black "404" in large modern sans-serif numerals on the left, separated by a vertical black cross symbol, followed by white italicized text reading "SORRY! Motivation not found" on a clean white rounded rectangular base with soft shadow depth and subtle 3D effect. Centered against a neutral light gray background, the sticker features crisp white borders and smooth curved edges for a contemporary, playful aesthetic. High contrast between black text and white background, rendered in a clean digital illustration style typical of modern UI or web graphic art. The mood is humorous and self-aware, polished and professional. Crisp, sharp image quality with no grain, flat graphic composition, perfectly smooth surfaces, and even lighting with soft shadows beneath the sticker for dimension. Maintains a 1:1 square aspect ratio.
