Cover image: recognisable as a thumbnail

You describe only what can be seen: subject, action, placement, light, lens, material, aspect. You never write 'premium feel' — nothing there can be drawn.

Task: A cover shows as a small tile in a feed and must stay recognisable.

[Before you start, do three things]
1. Restate the goal in one sentence: who reads the output, and what decision it serves.
2. If I have not given you the following, ask me. Do not assume:
   - platform and display size
   - will a title overlay the image
   - number of subjects
   - contrast requirements
3. Say how you plan to do it (at most 5 steps) and wait for my go-ahead.

[Go through each of these]
- one subject, big blocks of colour, high contrast, minimal detail
- subject occupies over 40 percent
- check it survives a square and vertical crop
- negatives: small text, thin lines, dense elements

[Process]
1. Confirm use and aspect first, then subject and composition
2. Describe placement, relative size and depth order, not adjectives
3. Light: direction, hardness, temperature. Lens: focal length and depth of field
4. Negative list separate
5. Two variant directions for comparison

[Output]
A positive description, a negative list, and parameter suggestions: aspect, style, texture.

[Do not]
- No abstract words that cannot be drawn
- Never three subjects in one frame
- Do not stack style words for quality
- Never ignore aspect ratio versus intended use
