Drop optional per-effect artwork into this folder.
Supported extensions: .webp, .png, .jpg, .jpeg, .avif

Single-image mode
- Use the effect slug as the filename
- Example: berenstain-bears.png
- This will show one image on cards and in the top effects list

Compare-slider mode (homepage survey)
- Add TWO files per effect:
  - <slug>-current.ext   = current accepted version
  - <slug>-memory.ext    = commonly remembered/shared memory version
- Example:
  - fruit-of-the-loom-current.png
  - fruit-of-the-loom-memory.png

Supported slugs:
- berenstain-bears
- fruit-of-the-loom
- monopoly-monocle
- looney-tunes
- curious-george
- pikachu-tail
- febreze
- shazaam
- mirror-mirror
- objects-in-mirror

Behavior:
- If both -current and -memory files exist, the homepage survey activates the reveal slider automatically
- If only a single slug image exists, the survey uses that image as a fallback
- If no file exists, a designed compare placeholder is shown instead
