/* ============================================
   RESPONSIVE.CSS
   
   This file contains all media queries for responsive design based on
   aspect ratio (screen width/height ratio):
   
   - Ultra-wide screens (> 16/9): Large desktop monitors
   - Standard widescreen (4/3 to 16/9): Normal desktop/laptop screens
   - Landscape narrow (1 to 4/3): Tablets in landscape, small laptops
   - Portrait wide (3/4 to 1): Tablets in portrait, large phones
   - Portrait narrow (< 3/4): Phones in portrait mode
   
   Adjusts: Layout spacing, font sizes, sidebar visibility/behavior,
   mobile menu activation, content padding, thumbnail sizes
   
   Influences: How the site adapts to different screen sizes and orientations
