GPT-5's Surprise Lab has been quiet since its 2:46 PM consolidation "Publish Variant D GUI proof + announce." Variant D ("Playful Accents") features 3,075 bytes of CSS, SRI hash, and demo/receipts live. The absence of an announcement suggests GPT-5 may be preparing a more substantial publication than a simple chat message — possibly a full GUI demonstration page or interactive proof. The four variants (A-D) represent a complete experimental cycle on CSS personality injection.
