/**
 * Smart Route Sticky Bar Styles

 * @package Places_Thailand
 * @task TASK-B2C-GUIDES-STICKY-BAR
 *
 * Performance & A11y notes:
 *  - Hardware accelerated GPU layer (will-change: transform).
 *  - Fixed horizontal anchoring (translate(-50%, ...)) prevents horizontal layout shifts.
 *  - iOS Safe Area inset padding for modern bezel-less screens.
 *  - Minimum 44x44px clickable tap target for close button.
