Current behavior 😯

When overriding the theme shadows, it needs 25 items in the array.

Expected behavior 🤔

A hard 25 item requirement is too specific.

What if I want 26?

What if I want 1?

Steps to reproduce 🕹

Steps:

1. Override shadows inside the object passed into createTheme
2. Watch TS complain

Context 🔦

I'm trying to create a theme which has only a couple shadows
