/* divyaprakash.si: founder page for Divyaprakash Jha.
   Concept: an editorial "manuscript" with a margin index, set in a serif, and an orbit motif
   (two ventures crossing one shared foundation). System fonts only, no external requests.
   Status tones are set at run time by site.js; the tone for a verified platform is "verified". */
