/* ── User Vignette — avatar circle + name inline component ────────────────────
 *
 * Reusable component that pairs a coloured initials circle with a display
 * name resolved asynchronously.  Used in:
 *  • Owner column (list view, SharedWithMe & Favorites sections)
 *  • ShareModal member rows, chips, suggestion items
 *  • User-menu toolbar button and dropdown header (avatar-only mode)
 *
 * Sizes: --xs (20 px) · --sm (24 px) · --list (36 px) · --md (32 px)
 *        --lg (40 px) · --menu (38 px) · --xl (48 px)
 * Colours: .uv-color-0..4  (applied by JS via _colorIndex(userId) % 5)
 *
 * All colours use CSS custom properties — no raw hex / rgb / named values.
