/**
 * TileLogo Component
 *
 * A tile/card component designed to display brand logos with interactive states.
 * Supports two shape variants (Square and Rectangle) and two color variants
 * (Neutral and Green) with five interaction states (Default, Hover, Focused,
 * Pressed, Disabled).
 *
 * Features a "window shade" hover animation where the hover color wipes from
 * bottom to top on mouse enter, and top to bottom on mouse leave.
 *
 * Shape sizes are responsive and change based on breakpoints:
 * - Square: 1:1 aspect ratio with responsive padding
 * - Rectangle: Fixed height (96px SM/MD, 160px LG) with responsive padding
 *
 * @example
 * // Basic usage with link (square shape - default)
 * <TileLogo
 *   variant="neutral"
 *   logo="/logos/partner-logo.svg"
 *   alt="Partner Name"
 *   href="/partners/partner-name"
 * />
 *
 * @example
 * // Rectangle shape with click handler
 * <TileLogo
 *   shape="rectangle"
 *   variant="green"
 *   logo="/logos/featured-logo.svg"
 *   alt="Featured Partner"
 *   onClick={() => openPartnerModal('featured')}
 * />
 *
 * @example
 * // Disabled state
 * <TileLogo
 *   variant="neutral"
 *   logo="/logos/coming-soon.svg"
 *   alt="Coming Soon"
 *   disabled
 * />
