// The kundali payload is grouped the way the app screens are: one key per tab,
// with the sub-sections nested underneath it. Every leaf holds the *unwrapped*
// "response" of its VedicAstroAPI endpoint, passed through untouched, so the
// vendor's own field names are what the client sees.
//
// Partial failure is by design. A leaf whose upstream call failed is omitted and
// named in CompleteKundaliResponse.Errors; the rest of the kundali still
// returns. Clients must treat any missing leaf as normal.
//
// A few sections are deliberately repeated across groups — personal
// characteristics under both Chart and Reports, mahadasha under both Dasha and
// Others — because that is how the screens read them. Each is fetched once and
// referenced twice.
