貝殼當寫字樓，晨光掃過每層

A giant spiral seashell stands in for a corporate office tower under soft morning light, its pearled whorls rising tower-high over a quiet plaza. Small glass office windows run in rows that trace the shell's spiral all the way from its broad base to its crown, and at ground level a revolving door turns inside an opening that belongs to the shell itself. Tiny office workers cross the plaza and file through that same door into the one continuous shell structure — their small scale is what confirms the shell really is the building. Hold the camera low, at a three-quarter angle, so the shell's curve reads as an architectural facade and the windows catch the morning sun in sequence as they wrap around the spiral. Leave every surface blank: no sign, no lettering, no logo anywhere — the plaza stones, door frame and window mullions stay unmarked, and the shell's own ridges carry no text at all. Fit the whole scene inside a 16:9 wide composition with clear margin around both the shell's crown and its base, rendered in a pale palette of pearl white, sandstone, glass blue and morning gold.
