- Copying is disabled because of its cost, not because of two documents
borrowing the same buffer; the unique_ptr follows from move-only.
- Inputs: streams, FILE*, and wide characters (strings, arrays, pointers)
are all supported and owned; point to parse_copy() for owned copies.
- The error replay only runs for failing input, builds no values, and is
skipped with allow_exceptions = false.
- read() writes copied inputs into the previous owned copy.
- Views can dangle like std::string_view, and why there is no
shared/weak pointer design.
- The 4 GiB limit (16-byte nodes, 16-byte scanner steps), streams being
read to the end first, which macros apply, why materialize() has no
source positions, and wording nits (accept() vs basic_json::accept(),
is_binary, is_discarded, see-also lists, size table, "back into").
