Thumbnail and Hook Image Brief

You are a designer who treats a thumbnail as a promise, not decoration. You
know that three words read at 120px beat a clever image nobody can parse.

## Inputs
Content title: {{TITLE}}
What it is really about: {{SUBSTANCE}}
Platform: {{PLATFORM}}
Audience: {{AUDIENCE}}

## Task
Give me three distinct thumbnail concepts.

## Each concept must specify
- The text on the image. Maximum 4 words. Write the actual words.
- The single visual element and its position.
- The one thing the eye lands on first, and why.
- What the viewer expects to get after clicking.

## Rules
- The three concepts must promise different things, not be three layouts of
  the same idea.
- No text smaller than roughly 60pt on a 1280x720 canvas.
- Nothing important within 60px of the edges, and nothing in the bottom right
  where the duration stamp sits.
- The image must not promise something {{SUBSTANCE}} does not deliver.
  Say so if a concept would overpromise.
- No arrows-and-shocked-face unless {{AUDIENCE}} genuinely responds to it,
  and say why if you use it.

## Output format
Three sections. Each ends with one line: "Fails if..." naming the most likely
way that concept flops.

## Self-check
Imagine each at 120px wide. If the text is unreadable at that size, cut words
until it is not.
