"Obliging Carp" は、釣りチャンネルのYouTubeサムネイルで、力強いアウトドア風です。暗いふちの大きな斜めの黄色い文字が朝焼けの霧の川の上にあり、隅に小さなシリーズのタグ、右下では金色のコイが水しぶきを上げて水面から跳ねています。自分の釣果と回のタイトルで作り直せます。

Create a 16:9 YouTube thumbnail with the exact visible text: primary headline "Obliging Carp"; small top-left series label "RIVER FILES"; small bottom-right descriptor "ANGLING STORY". Build for instant phone-screen legibility. Background: low-angle view across dark teal river water at sunset, a large mirror carp breaking the surface in the lower-right third, wet bronze-gold scales catching a narrow amber sun reflection; distant reed bank and tree line reduced to soft dark silhouettes, heavily blurred cityless horizon, sparse water droplets frozen in the air. Place the headline across the upper and center-left, occupying about 62% of the frame width over the cleanest dark-water area. Custom ultra-heavy, wide near-square display lettering, tight vertical spacing, near-zero stroke contrast, close-set characters. Letter fill: saturated electric yellow with subtle warm amber front light; every letter surrounded by a very thick matte-black hard outline and a short black drop shadow, with a thin cyan rim on the outer right edges. Set "Obliging" smaller above "Carp"; "Carp" is the dominant word, approximately twice the cap height. "RIVER FILES" is compact white uppercase with black outline in a small cyan-edged black capsule. "ANGLING STORY" is small white uppercase with black outline. Warm amber backlight blooms behind the carp and title; teal-blue shadows, deep charcoal vignette at edges, crisp foreground splash, shallow depth of field, thumbnail-grade contrast. Keep all text perfectly spelled, flat-on-camera, unobstructed, and clean; no extra words, no logos, no people.
