/* ==========================================================================
   ஐங்குறுநூறு · Aiṅkuṟunūṟu — Morning Gold & Forest Green Theme
   500 short akam poems · 5 poets · 5 tiṇai · c. 300 BCE – 300 CE
   One of the Eight Sangam Anthologies (Eṭṭutokai)

   Visual identity: morning-gold (warm Tamil dawn), deep forest-green,
   and five tiṇai accent-colours that map the five landscapes.

   The Aiṅkuṟunūṟu (ஐ = five + குறு = short + நூறு = hundred) is the
   most symmetrically organised of all the Sangam anthologies: exactly
   100 poems per tiṇai, each tiṇai by a single poet, all poems short
   (3–6 lines), all pure akam. It is a five-fold prism of Tamil love
   poetry — the same emotional world refracted through five landscapes,
   five voices, five seasons.

   The morning-gold palette: not the amber of royal courts (Patiṟṟuppattu),
   not the copper of wisdom (Nālaṭiyār), but the warm gold-green of the
   Tamil landscape at first light — the jasmine opening, the field damp
   with dew, the sea pale with dawn. Five petals, one flower.
