สไลด์ออกแบบผลิตภัณฑ์สไตล์ภาพร่างวิศวกรรม

A complete presentation slide layout designed in a modern engineering hand-drawn sketch style, reminiscent of Apple or Tesla industrial design drafts. Theme: "[Genius Youth in the AI Era]". Pure white background with abundant negative space. Delicate, precise technical drafting lines, dark gray handwritten titles, and engineering annotations outlining sequential steps. Simple line icons paired with clear step descriptions. Subtle, high-transparency watercolor washes in light blue, soft green, and pale orange accents. Clean, professional, and sophisticated technological aesthetic.
