/* ============================================================================
 * public/css/anime-mentor.css
 * Styling for the fixed bottom-left anime-style mentor mascot that overlays
 * the mission screen on /student/missions/<slug>. See public/js/anime-mentor.js
 * for the rotation pool + event integration. Palette mirrors the existing
 * .mentor-companion strip in public/css/app.css (dark glass #0f172a with the
 * #67e8f9 cyan accent) so the avatar reads as part of the same mentor family
 * rather than a parallel UI element.
 *
 * Stack-rank: 950 keeps it BELOW the floating #mentor-panel (z=1000) so the
 * existing chat panel still wins focus when the student opens it. Above the
 * generic mission card so it doesn't slip behind quiz UI on long pages.
