/* ==========================================================================
   LearnBox marketing landing page
   Built from Figma file gYUpuRb1YFRCPOqJYnKkao ("LearnBox (Copy)")
   Desktop frame (239:5268, 1440x9231) is reproduced as a fixed-width
   "stage" that is proportionally scaled to fit the viewport. The Tablet
   (239:7522, 768w) and Mobile (239:9024, 320w) frames in the source file
   are themselves uniform scale-downs of the desktop frame (no reflow /
   restacking / nav-collapse differences were present in their metadata),
   so scaling the stage reproduces all three breakpoints exactly.
   Sections stack in normal flow (position:relative + explicit height);
   every element inside a section is positioned absolute relative to
   that section's own top-left corner.
