   பழமொழி நானூறு · Paḻamoḻi Nāṉūṟu — Four Hundred Proverbs
   400 proverb-and-commentary verses · c. 1st–5th century CE
   Author: Muṉṟurai Araiyaṉār · Patiṉeṇkīḻkaṇakku collection

   Title: பழமொழி (paḻamoḻi) = proverb / old saying; நானூறு (nāṉūṟu) = four hundred.
   Each verse pairs a classical Tamil proverb with a venba commentary poem
   by Muṉṟurai Araiyaṉār that illuminates the proverb through illustration.
   The 400 verses are grouped into 11 sections: Araṉ, Poruḷ, Iṉpam, Vīṭu,
   Araci, Katci, Payaṉ, Naṭpu, Perumai, Ciṟumai, Tiṟam.

   Visual identity: Proverbs are ancient, dense, oral. They carry the weight
   of accumulated speech — passed mouth to mouth across generations. The
   palette draws from that world of accumulated speech and manuscript:
   deep midnight-blue (the dark before dawn — when elders speak),
   warm gold-amber (the lamp that illuminates the proverb),
   and worn-parchment (the leaf on which it is written).

   Mark: an open book / unrolled scroll — a palmleaf manuscript opening,
   two arcs meeting at a spine. Simple, immediate, unique in this library.
