/**
 * Toggle — WealthX DS overrides (shadcn base)
 *
 * Changes from shadcn default:
 *   - `rounded-md` removed — sharp corners per WealthX DS
 *   - `shadow-xs` removed from outline variant — flat panels
 *   - Pressed/on state uses `bg-primary/10` + `inset-ring-primary` + `text-foreground` via Figma tokens
 *     (inset-ring instead of border-primary so indicator is independent of border-width,
 *      works correctly inside ToggleGroup where border-l is collapsed for connected items)
