[6.x] `.bard-fullscreen` styles missing from dist build

[martyf]

Bug description

When opening a Bard field in Statamic 6, the background is missing.

The bard-fullscreen class is correctly added to the bard-fieldtype div, however there is no definition in the dist build.

In the Statamic 6 Alpha 19 install of the site, inspecting element and manually adding these styles resolves the issue:

.bard-fullscreen {
	position: fixed;
	inset: calc(var(--spacing) * 0);
	min-height: 100vh;
	overflow: scroll;
	border-radius: 0;
	--tw-border-style: none;
	border-style: none;
	background-color: var(--theme-color-gray-100);
	padding-top: calc(var(--spacing) * 14);
}

This .bard-fullscreen definition is what is missing in the dist version of the install process.

Statamic 6 Alpha 19:

In the Statamic 6 dev build (i.e. npm run dev) the issue is not present. It only appears in the dist build.

Statamic 6 dev build:

How to reproduce

1. Install Statamic 6 Alpha 19 (was also present in 18)
2. Add a Bard field to the Page Blueprint
3. Create an Entry, and open the Bard field as Full Screen
