/* RAG Hub — visual language ported from MNU Hub (HubDesignSystem.ru.md / HubColorScheme.ru.md).
   Light theme, single burgundy accent, soft large radii, mobile-first. Sidebar kept always-expanded
   (not hover-collapsing like Hub's desktop sidebar) — this panel only has two nav items, so a
   collapse/expand interaction would add complexity without a real payoff; the gradient/radius/float
   treatment and the mobile drawer are carried over as specified. */
