DESIGN BRIEF: The brief was to land a narrow-body jet inside Mithila line grammar without letting the machine read like clip art dropped on a folk border. Kachni made sense because the sky needed texture, not flat Bharni blocks — parallel hatch bands carry the climb vector the way Kayastha women once used line density to suggest shade on a courtyard wall. Diagonal-flow symmetry solves the layout problem: a centred bilateral plane would feel parked; an ascending left-to-right runway diagonal gives takeoff momentum while the four-sided border stays formally balanced like Kohbar wedding panels. We kept the A320 readable through silhouette — gear down, nose up, twin underwing engines — then folk-stylised the tail with a sunburst floral roundel so the aircraft belongs to the border vocabulary instead of fighting it. Terminal and tower sit mid-right as geometric anchors; the lower-left floral ground roots the scene in classical lotus-and-leaf motifs so the fusion reads as Mithila first, aviation second.
