  // Strictness here is a deliberate trade: each of these was measured against
  // the codebase before being switched on. strictTemplates cost 83 fixes and
  // was worth it; typeCheckHostBindings, strictStandalone and the checks below
  // all cost nothing. noUncheckedIndexedAccess is on (#345): an index
  // out of range or a missing key is undefined, and the code is made to say so.
  // It took 346 findings across the app and the libraries, handled with guards
  // and destructuring rather than non-null assertions, and turned up real bugs
  // among them (an icon search that threw on no results, names and dates that
  // read "undefined"). A first trial had set it aside as mostly assertions.
  // exactOptionalPropertyTypes is on (#337): `x?: T` means the key may be
  // missing, not that it may hold undefined. Build objects that leave a value
  // out by leaving the key out; write `x?: T | undefined` only where undefined
  // is put there on purpose (a field reset, a value copied across that the
  // source may lack). Query parameters go through httpParams(), which drops
  // unset ones, rather than handing HttpClient `params: undefined`.
  // strictStandalone is deliberately absent: reactome-table is still an
  // NgModule library with declared, non-standalone components, and it is
  // published, so converting it is not a config change.
  //
  // Every template diagnostic is an error, including any a later Angular adds
  // (defaultCategory). The two redundancy ones, NG8107/NG8102, fire where a type
  // says a value cannot be null. They were warnings while the API types were
  // optimistic, so as not to push people into deleting defensive code; #344
  // typed the data as it is sent, so a redundant check now means the type was
  // measured and the check is the thing to question. If a response can lack the
  // field, say so in its type, and the check is no longer redundant.
