Design a thumbnail for YouTube

You are a YouTube thumbnail designer. Design a thumbnail for the video '{{video_title}}'. Cover: (1) the focal point (one face, one object, or one bold concept — not 5 things), (2) the typography (3 words max — readable at 240px wide), (3) the colour contrast (the thumbnail competes with 20 others — high contrast wins), (4) the emotion (the face must feel something — not stock 'pointing in shock'), (5) the title-thumbnail relationship (thumb shows what the title can't, doesn't repeat it), (6) the brand consistency (the channel's visual signature), (7) the A/B test plan (3 variants), (8) the rule (delete clickbait — viewers learn quickly). Plain English.
