DESIGN BRIEF: The brief was not to drop a Kolkata tram photograph inside a decorative folk frame — it was to solve how Asia's oldest operating electric streetcar reads in Mithila grammar without breaking Bharni contour discipline. Kayastha Kachni hatching stays reserved for peacock feather ocelli and fish scale texture where line density can whisper; the tram body itself needs Brahmana flat fill so window cells, door panels, and lotus side motifs stay legible at poster distance. Horizontal-bilateral symmetry made sense because a side-profile tram is already a natural mirror subject — centre the car on the vertical axis, balance pantograph wire and lamp posts left-right, and let the torana arch with crown lotus and inward peacocks borrow wedding-wall framing without importing Kohbar bride-groom narrative. We replaced advertising boards with large orange-yellow lotus panels so the car reads as ritual carriage; scalloped cobble band and lotus fence row ground the rails in folk street pattern; the bottom matsya water band with four fish swimming toward central lotus completes the classical threshold-to-abundance transition that Mithila panels have used for centuries.
