Create a vertical 4:5 (1080x1350) mixed-style visual: 30% cinematic + 40% illustration + 30% social media. A clean, modern flat-lay composition showing a smartphone screen displaying WhatsApp chat bubbles with pre-written sales scripts. Floating paper notes or sticky memos with checklist items "COPY → PASTE → SEND" in Indonesian. A subtle glowing blue accent (#2563EB) around the phone. Light cream background (#FAFAFA) with subtle gradient. Small decorative elements: floating chat bubbles, paper planes, subtle sparkles. Bottom area leaves space for text overlay. Professional but approachable vibe. Metaphor: "instant tools ready to use" — like a toolbox or quick-reference cards. Modern tech illustration style with warm undertones.
