Slate Digital Smart Pen

Elegant product photography of a slim matte-black smart pen called 'Slate Ink' resting diagonally on a dotted notebook, a faint blue LED near the tip indicating active digitizing. Warm desk lamp light from the right, moody dark-academia palette with deep browns and soft shadows, a blurred laptop syncing in the background. Sophisticated creator-tech ad mood, close-up 45-degree angle, shallow depth of field, 16:9 wide. Small tagline: 'Write once, everywhere.'
