/* Agent Airlines · styles
   Built to Apple's Human Interface Guidelines where they apply to the web:
   - the system font (SF Pro on Apple devices), few type sizes, rem units so text scales with the browser
   - iOS dark system colours; a permanently dark appearance, which the HIG allows for immersive media
   - contrast of at least 4.5:1 for text, 44 pt hit targets, visible keyboard focus
   - safe areas, layouts that stack instead of truncating, Liquid Glass only on the navigation layer
   - Reduce Motion, Increase Contrast and Reduce Transparency respected */
