// ==============================|| STAT / KPI CARD ||============================== //
//
// Ultra-compact, dense, space-efficient enterprise KPI component.
// Shared across Deliveries, Orders, Pricing, Tenants, Riders, Customers, Hubs,
// Vehicles, Tripsheets, Exceptions, App Users, Reports and Dispatch.
//
// ---------------------------------------------------------------------------
// ULTRA-COMPACT HORIZONTAL COMPOSITION (~48px target height)
// ---------------------------------------------------------------------------
// 1. Icon chip: 26px × 26px with 6px radius and subtle 7% tint (`${accent}12`).
//    Glyph size normalized to 14px.
// 2. Value: 18px bold (`lineHeight: 1`, `fontVariantNumeric: 'tabular-nums'`).
// 3. Label: 12px / 500 in secondary ink (`#64748b`), aligned horizontally on
//    the same baseline beside the value for maximum space efficiency and instant
//    (<1s) visual scanning.
// 4. Tight elevation, flat white surface, 8px rounded corners, 7px 12px padding.
// 5. Interactive/clickable hover support with smooth 150ms transition. Static
//    cards remain clean without hover distraction.
// ---------------------------------------------------------------------------
