/**
 * Simple LMS Front-End Stylesheet
 *
 * @package Simple_LMS
 * @version 20251112.1855 (Gemini - Phase 4: Polish)
 *
 * This file contains all styles for:
 * 1. The [slms_course_dashboard] shortcode
 * 2. The [slms_course_tile] shortcode
 * 3. The single-slms_course.php course player template
 *
 * CHANGELOG:
 * - Phase 4: Polish
 * - `.slms-player-wrapper`: Added `height: 85vh;` to give the
 * - entire player a consistent height.
 * - `#slms-content-area`: Removed `min-height` and `max-height`
 * - to allow flexbox to control the height and scrolling.
 * - `@media (max-width: 768px)`: Added `height: auto;` to
 * - `.slms-player-wrapper` to disable the fixed height on mobile.
 *
 * - Phase 4: Polish
 * - `.slms-nav-course-thumb img`: Changed fixed `height` to
 * - `max-height` and `max-width` to respect aspect ratio
 * - of the new custom navigation image.
