Japanese Video Overlay Subtitle Banner

A decorative Japanese lower-third banner graphic for short video overlays, isolated against a subtle light-gray checkerboard transparency preview pattern, wide horizontal layout. The main element is a cream-white rounded rectangular speech-bubble plaque spanning most of the width, featuring layered offset drop shadows, thin gold, and pale blue outlines in a vintage Japanese stationery aesthetic. On the upper left tab, a small circular laptop icon with code brackets accompanies the Japanese label "[開発者コメント]". Centered on the plaque is an elegant Japanese Mincho-style calligraphy headline reading "[ハイネを消す方法]", with the characters "消す" colored in muted blue and the remaining text in black, underscored by exactly 1 thin blue wavy stroke. On the left inside the plaque, exactly 1 pale blue-gray watercolor dolphin illustration faces right. Overlapping the upper right edge, exactly 1 scalloped comic burst sticker in beige with handwritten sound effect text "[ピコン]" and exactly 2 exclamation mark accent rays. Decorative accents include exactly 6 small sparkle stars around the dolphin and headline, exactly 4 tiny dots near the lower-right center, subtle beige halftone dot textures on the sides, and delicate gold corner flourishes. Soft pastel cream, dusty blue, and muted gold color palette with clean vector outlines and soft drop shadows. Constraints: no people or figures, no extra text, generous readable spacing.
