Acrylic keychains

Acrylic keychains are one family with two immutable size variants.

Product ID	Physical output	Required front and back ratio
`acrylic-keychain-small`	1.5 × 1.875 inches	`4:5`
`acrylic-keychain-large`	3 × 2.125 inches	`7:5`

Both front and back are required once and have fixed orientation. Prepare the two sides independently. Do not combine them into an artwork asset.
