   Aṣṭādhyāyī study edition — design system

   Colour is functional, never decorative. Five hues, one per kind of grammatical
   statement, drawn from manuscript-tradition pigments. NOTHING ELSE on this site is
   coloured, so hue always means rule-type. That is the single most useful thing a
   beginner internalises here, so it is load-bearing — do not spend these hues on
   anything else, and do not add a sixth.

   Type: Tiro Devanagari Sanskrit for Devanāgarī (drawn for Sanskrit, carries Vedic
   accent marks), Spectral for Latin body, IBM Plex Mono for sūtra addresses —
   because addresses are coordinates, not prose. No fourth family.

   Restraint: one bold element (the sthāna strip), everything else quiet. No
   gradients, no shadows, no decorative animation.
