An error page that plays it completely straight, then pivots — 'the deal you were looking for moved here.'
Vertical 4:5 static ad styled as a generic website error page — pixel-clean flat UI, generous whitespace, no browser chrome, no phone bezel. Top left: small text wordmark "[BRAND — e.g. "Stitchfold"]" in quiet grey sans. Center: an enormous "404" in ultra-bold black sans filling a third of the frame, with the middle "0" replaced by [PRODUCT MOTIF — e.g. "a neatly coiled ring of oatmeal-colored knit fabric"]. Beneath it in medium grey: "Page not found." Then the pivot line in bold black: "But the 30% off you were looking for moved here." Below: a single rounded black button with the white label "Take me to the deal", and under it tiny monospaced grey text "Error code: FOMO_PREVENTED". Footer: hairline rule with small grey links "Home Shop Help". Typography is dry, modern, startup-clean — the joke lands because everything else is played completely straight. One accent element only, huge negative space, perfect kerning on the "404". No real error-page or hosting branding, no watermark, no illustration clutter, all text crisp and correctly spelled.
