/*
 * RBTHelper shared component header — Wave 6 visual alignment
 *
 * Scope is still limited to elements carrying the rbth-component-header class
 * family; component bodies keep their own CSS, content, and behavior. Wave 6
 * restyles this chrome to match the v2 site shell: self-hosted brand
 * typography, the v2 accent bar and tint wash, softer radii, and the v2
 * control language. Per-component accent tokens are unchanged, and every
 * accessibility guarantee from the Wave 4B.1 pilot is preserved: 44 CSS-pixel
 * minimum control targets, visible focus, static positioning, wrapping
 * actions, both responsive breakpoints, and reduced-motion support.
