Skill: Space items out evenly (justify-evenly & gap)

Using `justify-evenly` (Row)

`justify-evenly`: Equal space between each item, and also between the first/last items and the container edges.

Item 1
Item 2
Item 3

Using `gap-4` (Row)

`gap-4` (equivalent to `gap: 1rem`): Adds a consistent space *between* flex or grid items. Does not add space at the start/end of the container.

Item A
Item B
Item C

Using `gap-4` (Column)

`gap-4` also works for columns, creating vertical space between items.

Item X
Item Y
Item Z
