Z-index pixel unit

[KatsanKat]

Hello !
I noticed from the playground theme that the zIndex values are written in pixel unit :

pinceau/playground/theme/tokens.config.ts

Lines 248 to 270 in 28a05cf

	zIndex: {
	0: '0',
	1: '1px',
	2: '2px',
	4: '4px',
	6: '6px',
	8: '8px',
	10: '10px',
	12: '12px',
	16: '16px',
	20: '20px',
	24: '24px',
	32: '32px',
	40: '40px',
	44: '44px',
	48: '48px',
	56: '56px',
	64: '64px',
	80: '80px',
	104: '104px',
	140: '140px',
	200: '200px',
	},

Since the mdn doc specified that z-index only supports integers,
is there a particular reason you choosed to define it with px or is it a mistake ?

This should be a copy-paste error. I noticed that the value of z-index is the same as the value of space, so it was likely copied by mistake. I made a PR for this. https://github.com/Tahul/pinceau/pull/69/files
