/*
 * Detail Card - Base Styles
 * =========================
 * Reusable card component for displaying detailed information.
 * Used by three UX patterns: inline expand, slide-in panel, and modal.
 *
 * BEM Structure:
 * - .detail-card (block)
 * - .detail-card__header, __body, __traits (elements)
 * - .detail-card--inline, --panel, --modal (modifiers)
