* docs: cross-reference json_view and json_document for 3.13.0 Document the new zero-copy document/view API across the docs: add a "Documents and views" section to the basic_json API hub linking to all specializations, point parsing/conversion/modifying pages to the view-based alternatives, add document/view sections to feature pages, update the landing page to mention json_view.hpp/json_literals.hpp, and cross-link debugging/exceptions. Also document wide-string inputs (and ill-formed UTF-16/32 rejection), add parse/accept examples for wide strings, fix related doc gaps, and align features/parsing and FAQ with the added support. Signed-off-by: Niels Lohmann <mail@nlohmann.me> * docs: fix article before std::istream in FAQ Signed-off-by: Niels Lohmann <mail@nlohmann.me> * docs: clarify document inputs, decoding, get<T>() and editing Address review comments: say which inputs are borrowed and that a wide string pointer is an extra input, which values are decoded during parsing, that get<T>() reads only built-in types directly, all forms of set() and that the document's insert() is array-only, and how to store wide strings. Signed-off-by: Niels Lohmann <mail@nlohmann.me> * docs: integers are converted while parsing a document Also say "They accept every input" in basic_json_document::parse.
