   own_classifieds - Apple Design System (HIG & Craft Refinements)
   Grounded in Apple Human Interface Guidelines:
   - Typography: -apple-system / SF Pro Font Stack, Text Hierarchy & Tracking
   - Liquid Glass & Translucency: backdrop-filter Blur, Subtle Borders & Specular Highlights
   - Modern Form Controls: 10px-12px Squircle Radius, Smooth Focus Ring (SF Blue)
   - Depth & Shadows: Multi-layered, soft ambient occlusion instead of harsh drop shadows
   - Tactile Feedback & Micro-interactions: Active button scaling, smooth Bezier curves
