“1ro A sec.” is a FontVibe AIで作成した文字エフェクト.

A vertical concert-poster composition for the exact text "1ro A sec.", centered as the single hero element with generous empty space around it. Set the scene inside a dark underground transit platform after rain: matte charcoal concrete walls, a thin strip of wet black tile at floor level, distant tunnel receding behind the composition. Place a small analog platform clock far in the upper-left background and a blurred departure board far right, both reduced to indistinct light shapes so no additional readable words appear. The central text occupies nearly 60% of the frame height, arranged on two lines: "1ro" large on the first line, "A sec." slightly smaller beneath it, aligned center with a tight, intentional gap. Behind the text, a broad oval pool of reflected cyan, violet, and magenta light spreads across wet pavement without touching the characters. Atmospheric rain haze hangs low near the floor; individual raindrops catch narrow backlight. Use a near-black background, deep perspective, controlled bloom in the environment, crisp focus on the text, and subdued peripheral detail. No extra typography, logos, symbols, or decorative objects in the foreground.
