/**
 * useStatusBar - Headless hook for managing status bar interactions and keyboard navigation
 *
 * This hook provides the core logic for StatusBar interactions, implementing a
 * headless UI pattern that separates state management from presentation. It handles:
 *
 * **Interaction Modes**:
 * - **hover**: Desktop hover state (shows card on mouse hover, auto-hides on leave)
 * - **pin**: Pinned state (click to pin card open, click again or Esc to close)
 * - **focus**: Keyboard focus state (shows card while focused, hides on blur)
 *
 * **Keyboard Navigation**:
 * - **Arrow Left/Right**: Navigate between bars in the same timeline
 * - **Arrow Up/Down**: Navigate between timelines (different monitors)
 * - **Enter/Space**: Pin/unpin the active bar
 * - **Escape**: Close pinned card and remove focus
 *
 * **Touch Device Support**:
 * - Disables hover state on touch devices (detected via `(hover: none)` media query)
 * - Click interaction works on both touch and non-touch devices
 *
 * **Outside Click Handling**:
 * - Automatically closes pinned cards when clicking outside the component
 *
 * @param dataLength - Total number of bars in the timeline
 * @param isTouch - Whether the device supports touch (no hover capability)
 *
 * @returns Hook state and handlers:
 * - `activeIndex`: Currently active bar index (null if none)
 * - `isOpen`: Whether a card is currently displayed
 * - `interactionType`: Current interaction mode ("pin" | "hover" | "focus" | null)
 * - `containerRef`: Ref for the status bar container (for outside click detection)
 * - `handlers`: Event handler functions for mouse/keyboard/focus interactions
 * - `setButtonRef`: Function to register bar element refs (for keyboard navigation)
 *
 * @example
 * ```tsx
 * function CustomStatusBar({ data }) {
 *   const isTouch = useMediaQuery("(hover: none)");
 *   const { activeIndex, handlers, setButtonRef, containerRef } = useStatusBar({
 *     dataLength: data.length,
 *     isTouch,
 *   });
 *
 *   return (
 *     <div ref={containerRef} role="toolbar">
 *       {data.map((item, index) => (
 *         <button
 *           key={index}
 *           ref={(el) => setButtonRef(index, el)}
 *           onClick={() => handlers.onClick(index)}
 *           onFocus={() => handlers.onFocus(index)}
 *           onKeyDown={(e) => handlers.onKeyDown(e, index)}
 *         >
 *           {// Custom bar rendering}
 *         </button>
 *       ))}

/**
 * StatusBar - Interactive uptime timeline with keyboard navigation and hover cards
 *
 * Displays a horizontal timeline of status bars, where each bar represents a day's
 * status with color-coded segments. Interactive hover cards show detailed status
 * information, events, and incidents for each day.
 *
 * **Key Features**:
 * - **Visual Timeline**: Vertical bars with color-coded segments showing status over time
 * - **Interactive Cards**: Hover/click to see detailed breakdowns and events
 * - **Keyboard Navigation**: Full keyboard support with arrow keys, Enter, and Escape
 * - **Touch Support**: Optimized interactions for touch devices
 * - **Customizable Rendering**: Override default renderers for bars, cards, and events
 * - **Accessibility**: ARIA roles, labels, and keyboard navigation
 *
 * **Interaction Modes**:
 * - Desktop: Hover to preview, click to pin, Esc to close
 * - Touch: Tap to toggle card open/closed
 * - Keyboard: Arrow keys to navigate, Enter/Space to pin, Esc to close
 *
 * **Keyboard Navigation**:
 * - **Left/Right Arrows**: Move between bars in the timeline
 * - **Up/Down Arrows**: Navigate between different monitor timelines
 * - **Enter/Space**: Pin or unpin the active card
 * - **Escape**: Close card and remove focus
 *
 * **Data Structure**:
 * Each data item represents a day and contains:
 * - `day`: Date string
 * - `bar`: Array of segments with status and height percentage
 * - `card`: Array of status breakdowns to display in hover card
 * - `events`: Array of incidents/maintenance events for that day
 *
 * @param data - Array of status bar data items (one per day)
 * @param renderCard - Optional custom renderer for card content items
 * @param renderBar - Optional custom renderer for bar segments
 * @param renderEvent - Optional custom renderer for event badges
 *
 * @example
 * // Basic usage with default rendering
 * ```tsx
 * const uptimeData = [
 *   {
 *     day: "2024-01-15",
 *     bar: [{ status: "success", height: 100 }],
 *     card: [{ status: "success", value: "100%" }],
 *     events: []
 *   },
 *   {
 *     day: "2024-01-16",
 *     bar: [
 *       { status: "success", height: 80 },
 *       { status: "error", height: 20 }
 *     ],
 *     card: [
 *       { status: "success", value: "80%" },
 *       { status: "error", value: "20%" }
 *     ],
 *     events: [
 *       {
 *         id: "inc-1",
 *         type: "incident",
 *         name: "API Downtime",
 *         from: new Date("2024-01-16T10:00:00Z"),
 *         to: new Date("2024-01-16T10:30:00Z")
 *       }
 *     ]
 *   }
 * ];
 *
 * <StatusBar data={uptimeData} />
 * ```
 *
 * @example
 * // With custom bar renderer
 * ```tsx
 * <StatusBar
 *   data={uptimeData}
 *   renderBar={(segment, index) => (
 *     <div
 *       key={index}
 *       className="w-full transition-all"
 *       style={{
 *         height: `${segment.height}%`,
 *         background: `linear-gradient(to top, ${statusColors[segment.status]}, transparent)`
 *       }}
 *     />
 *   )}
 * />
 * ```
 *
 * @example
 * // With custom event renderer
 * ```tsx
 * <StatusBar
 *   data={uptimeData}
 *   renderEvent={(event, index) => (
 *     <Link key={index} href={`/incidents/${event.id}`}>
 *       <div className="text-sm hover:underline">
 *         {event.name}
 *       </div>
 *     </Link>
 *   )}

 *
 * Returns null if no start date is provided.
