blog-thumbnail-generator

Make a 1:1 블로그 썸네일 (square blog/SNS thumbnail, 1000×1000 → exported as a 2000×2000 PNG) from a user-supplied photo plus short Korean text — a 제목(title), 카테고리(category), and 주제/키워드(topic keyword). The signature look: the photo fills the whole square uncovered, and the text sits in a bottom gradient band with a sky-blue + white palette (강조는 하늘색). Built with self-contained HTML/CSS and rendered to an image with Playwright. Use this skill whenever the user wants a 블로그 썸네일 / 썸네일 / thumbnail / 대표 이미지 / 표지 이미지 for a blog post or SNS, ESPECIALLY when they hand over a photo and want title/category/topic text on it — even if they just say "이걸로 썸네일 만들어줘", "이미지 업로드 했으니 썸네일 뽑아줘", or drop an image with a 제목·카테고리·주제. Also use it to re-render after changing text, swapping the photo, or tweaking the accent color while keeping the same look. Prefer this skill over ad-hoc HTML so every thumbnail stays on-brand and consistent.
