Clean modern editorial illustration for a French high-school engineering course, flat semi-realistic style, restrained palette of slate blue (#3C5460), teal (#0090A8) and a single warm red-orange accent (#E43C24), soft light background, generous negative space, no text, no logos, no watermark, high detail, 16:9 vertical. [style] A bright, aspirational hero image: a French teenager's hands assembling a small mechatronic prototype on a workbench — 3D-printed parts, a small motor, wiring and a microcontroller — shallow depth of field, morning light, optimistic and inviting mood.
