The Reference Image Prompt

Use reference images effectively on this platform.

Platform: [NAME]
Reference features available: [STYLE REFERENCE / CHARACTER
REFERENCE / FIRST FRAME / LAST FRAME / MOTION REFERENCE]
What I want the reference to control: [DESCRIBE]

Produce:
1. What each reference type actually controls
2. Which one fits my goal
3. What the reference image should contain
4. How much the text prompt should repeat what the reference shows
5. Where reference and prompt will conflict, and which wins
6. How strongly to weight the reference, if adjustable

Then:
7. Common mistakes with this reference type
8. What to do when the reference is being ignored
9. What to do when the reference is dominating and the prompt is
   being ignored

Mark anything you are uncertain about for me to verify — reference
feature behaviour differs by platform and changes between versions.
