In the classical definition "काव्य की शोभा बढ़ाने वाले धर्मों को अलंकार कहते हैं", what is the meaning of the word 'धर्म' (Dharma)?

In Acharya Dandi's famous rhetorical definition, the word 'धर्म' does not refer to religion or ritualistic duties. Instead, it signifies the structural qualities, attributes, or traits (गुण / विशेषताएँ) that enhance the beauty and expressive power of poetry.
