Add @media print rule to flyout Shadow DOM CSS to prevent the version selector from appearing in printed documentation or PDF exports. The flyout overlaps content when printing, making documentation hard to read. This fix uses @media print with :host selector to hide the entire Shadow DOM component during print.

Good catch, thanks for the fix! I think we can keep the rule but skip !important precedence overriding, that should still work.

!important shouldn't be needed here. We avoid !important, it's usually the source of precedence errors and it's hard to track down and resolve.
