科技教程缩略图及 UI 模型

A clean modern YouTube thumbnail on a bright white background, split visually between bold text on the left and a cropped presenter on the right. On the left, place a massive stacked headline in heavy black sans-serif uppercase reading {argument name="headline text" default="CLAUDE DESIGN"}, aligned top-left across two lines. Below it, add a large rounded rectangular orange banner with a subtle drop shadow containing bold white uppercase text with an orange outline that reads {argument name="subheadline text" default="IN 6 MINS"}. Near the headline, include 2 orange starburst spark shapes, one small beside the text and one much larger in the far right background. In the lower-left quadrant, show a floating app interface mockup for a design tool dashboard with a soft off-white panel, thin borders, rounded corners, and a faint shadow. The interface should have a left sidebar with 4 menu items labeled exactly: "Recent", "Your designs", "Examples", and "Design systems". The main panel header should say "Recent" and contain 3 project cards arranged in a grid, labeled exactly: "Thumio Design System", "Thumio Startup", and "Design System". On the right half, show a cropped photorealistic young adult man from chest up wearing a white turtleneck sweater, with messy light brown hair and light facial hair, positioned close to camera. His face is intentionally obscured by a solid tan rectangle placeholder covering most of the face area. He points with one hand toward the interface panel on the left, finger extended. Use a warm orange and white brand palette, high contrast, minimal clutter, polished creator-economy thumbnail styling, subtle shadows, and a composition designed for tech tutorial content.

一张简洁现代的 YouTube 缩略图，采用明亮的白色背景，视觉上分为左侧的粗体文字和右侧的半身演示者。在左侧，放置一个巨大的堆叠式标题，使用加粗的黑色无衬线大写字母，内容为 {argument name="headline text" default="CLAUDE DESIGN"}，左对齐并分两行显示。在其下方，添加一个带有细微投影的大型圆角橙色横幅，内含加粗的白色大写文字，并带有橙色轮廓，内容为 {argument name="subheadline text" default="IN 6 MINS"}。在标题附近，加入 2 个橙色星爆形状，一个较小，位于文字旁，另一个较大，位于远处的背景右侧。在左下象限，展示一个设计工具仪表盘的悬浮应用界面模型，面板呈柔和的灰白色，带有细边框、圆角和淡淡的阴影。界面左侧边栏应包含 4 个菜单项，标签分别为：“Recent”、“Your designs”、“Examples” 和 “Design systems”。主面板标题应显示为 “Recent”，并包含 3 个网格排列的“项目”卡片，标签分别为：“Thumio Design System”、“Thumio Startup” 和 “Design System”。在右半部分，展示一位胸部以上的写实风格年轻男性，身穿白色高领毛衣，留着凌乱的浅棕色头发和浅浅的胡茬，位置靠近镜头。他的脸部被一个覆盖大部分区域的纯棕色矩形占位符刻意遮挡。他的一只手指向左侧的界面面板，手指伸出。采用温暖的橙白品牌配色，高对比度，极简布局，精致的创作者经济缩略图风格，带有细微阴影，构图专为科技教程内容设计。
