/**
 * Top bar — single 64px black bar consolidating logo, bucket dropdowns,
 * right-side action cluster (perspective, feedback, dice, profile menu).
 *
 * Replaces the prior three-row stack of eyebrow + masthead + nav.
 * Inspired by D&D Beyond's nav. See docs/4_operations/nav-restructure-plan.md.
 *
 * The bar uses hardcoded dark hex values (not theme tokens) so it stays
 * black even when the user has selected the light theme — DDB's nav has
 * the same theme-independent dark treatment.
