   கார் நாற்பது · Kār Nāṟpatu — Forty on the Rains
   40 akam love poems on the kār (rainy) season · c. 1st–5th century CE
   Author: Matturai Marutaṉ Iḷanākaṉār · Patiṉeṇkīḻkaṇakku collection

   Title: கார் (kār) = the rainy season / monsoon; நாற்பது (nāṟpatu) = forty.
   Forty akam poems on the kār season — the season of reunion in the mullai tiṇai.

   Visual identity: The kār season is dark cloud, cool rain, the smell of wet earth,
   jasmine in the dark. It is the season lovers return; it carries the weight of
   waiting rewarded. The palette draws from that world:
   — deep rain-blue (the sky when the monsoon comes — dark, full, charged)
   — jasmine-white/cream (the mullai flower, the scent of reunion)
   — rain-green (the forest leafing out, everything suddenly lush)
   — wet-earth ochre (the smell of the first rain on dry ground)

   Mark: a rain-cloud arc with falling drops — simple, seasonal, immediate.
   Unlike the geometric marks of the ethical works, this is natural, flowing.
