How To Set Default Color In Tailwindcss 4 For A Rails App

Application.css looks like this:

```css
@import "tailwindcss";

@theme {
	--brand-color: oklch(0.35 0.2153 266.44);
}

@layer base {
	html {
		@apply text-(--brand-color);
	}
}

so the color gets defined in the @theme directive, and it then gets applied by the base layer.

There are other ways, but this seems to me the cleanest, and when universally needed, the right choice.

Maybe when dynamic application of themes is important, it might be easier to manipulate the body tag like so:

<body class="text-{color}">

wwwwwwwwwwwwwwwwwyou might still have to define the color somewhere if it is a custom choice.
