A vertical 3:4 advertising composition built around a clean smartphone-on-desk workspace. Place the exact text "免费试用" large and centered in the upper-middle area, arranged on one line with ample breathing room around every character; it is the only readable text in the image. Behind it, use a softly defocused pale warm-gray wall with a broad blank central panel, framed by a thin strip of cobalt-blue painter’s tape at the top edge and a small taped paper corner at lower right. Along the bottom quarter, show a matte white desk surface with a partially visible tablet, a capped marker pen, several small torn sticky-note rectangles with no writing, and a clear glass holding two pencils. Add a single cobalt-blue ceramic cup at the far left and a small sunlit plant leaf entering from the far right edge. Daylight falls diagonally from an off-frame window at upper left, casting soft-edged realistic shadows across the desk; faint cool-blue reflected light separates the blank wall from the foreground. Keep the center behind the text uncluttered and evenly lit for maximum legibility. Camera is straight-on with a slight elevated angle, shallow depth of field focused on the text plane, crisp commercial product-photography detail, natural paper fibers, subtle dust motes in the sunbeam, restrained palette of off-white, graphite, cobalt blue, and muted green.
