   Structure: ma (間) negative space + letterbox 2.35:1 + envelope stacks
   Motif: flowing copperplate curves + a scroll-drawn postal route line
   Interaction System* System System: System:** Interactive buttons and CTAs are styled as wax seal impressions — circular elements with a subtle embossed texture (CSS radial gradients and box-shadows creating a 3D stamp effect through Intersection Observer. The line should feel hand-drawn — use a slight waviness in the SVG path data. Space Grotesk" (400/500
