-- `publish_documentation.yml` — build and publish the documentation on pushes to the `develop` branch that touch the documentation sources (or the files it embeds).
-- `check_docs_links.yml` — check the links of the documentation weekly, as external links can break without any change in this repository.
-- `cancel_closed_pr_runs.yml` — cancel unfinished workflow runs of a pull request once it is closed or merged.

-
-    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
-    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
-    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
-    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES

-    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
-    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
-    HEREUNDER.
-
-Statement of Purpose
-
-The laws of most jurisdictions throughout the world automatically confer
-exclusive Copyright and Related Rights (defined below) upon the creator
-and subsequent owner(s) (each and all, an "owner") of an original work of
-authorship and/or a database (each, a "Work").
-
-Certain owners wish to permanently relinquish those rights to a Work for
-the purpose of contributing to a commons of creative, cultural and
-scientific works ("Commons") that the public can reliably and without fear
-of later claims of infringement build upon, modify, incorporate in other
-works, reuse and redistribute as freely as possible in any form whatsoever
-and for any purposes, including without limitation commercial purposes.
-These owners may contribute to the Commons to promote the ideal of a free
-culture and the further production of creative, cultural and scientific
-works, or to gain reputation or greater distribution for their Work in
-part through the use and efforts of others.
-
-For these and/or other purposes and motivations, and without any
-expectation of additional consideration or compensation, the person
-associating CC0 with a Work (the "Affirmer"), to the extent that he or she
-is an owner of Copyright and Related Rights in the Work, voluntarily
-elects to apply CC0 to the Work and publicly distribute the Work under its
-terms, with knowledge of his or her Copyright and Related Rights in the
-Work and the meaning and intended legal effect of CC0 on those rights.
-
-1. Copyright and Related Rights. A Work made available under CC0 may be
-protected by copyright and related or neighboring rights ("Copyright and
-Related Rights"). Copyright and Related Rights include, but are not
-limited to, the following:
-
-  i. the right to reproduce, adapt, distribute, perform, display,
-     communicate, and translate a Work;
- ii. moral rights retained by the original author(s) and/or performer(s);
-iii. publicity and privacy rights pertaining to a person's image or
-     likeness depicted in a Work;
- iv. rights protecting against unfair competition in regards to a Work,
-     subject to the limitations in paragraph 4(a), below;
-  v. rights protecting the extraction, dissemination, use and reuse of data
-     in a Work;
- vi. database rights (such as those arising under Directive 96/9/EC of the
-     European Parliament and of the Council of 11 March 1996 on the legal
-     protection of databases, and under any national implementation
-     thereof, including any amended or successor version of such
-     directive); and
-vii. other similar, equivalent or corresponding rights throughout the
-     world based on applicable law or treaty, and any national
-     implementations thereof.
-
-2. Waiver. To the greatest extent permitted by, but not in contravention
-of, applicable law, Affirmer hereby overtly, fully, permanently,
-irrevocably and unconditionally waives, abandons, and surrenders all of
-Affirmer's Copyright and Related Rights and associated claims and causes
-of action, whether now known or unknown (including existing as well as
-future claims and causes of action), in the Work (i) in all territories
-worldwide, (ii) for the maximum duration provided by applicable law or
-treaty (including future time extensions), (iii) in any current or future
-medium and for any number of copies, and (iv) for any purpose whatsoever,
-including without limitation commercial, advertising or promotional
-purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
-member of the public at large and to the detriment of Affirmer's heirs and
-successors, fully intending that such Waiver shall not be subject to
-revocation, rescission, cancellation, termination, or any other legal or
-equitable action to disrupt the quiet enjoyment of the Work by the public
-as contemplated by Affirmer's express Statement of Purpose.
-
-3. Public License Fallback. Should any part of the Waiver for any reason
-be judged legally invalid or ineffective under applicable law, then the
-Waiver shall be preserved to the maximum extent permitted taking into
-account Affirmer's express Statement of Purpose. In addition, to the
-extent the Waiver is so judged Affirmer hereby grants to each affected
-person a royalty-free, non transferable, non sublicensable, non exclusive,
-irrevocable and unconditional license to exercise Affirmer's Copyright and
-Related Rights in the Work (i) in all territories worldwide, (ii) for the
-maximum duration provided by applicable law or treaty (including future
-time extensions), (iii) in any current or future medium and for any number
-of copies, and (iv) for any purpose whatsoever, including without
-limitation commercial, advertising or promotional purposes (the
-"License"). The License shall be deemed effective as of the date CC0 was
-applied by Affirmer to the Work. Should any part of the License for any
-reason be judged legally invalid or ineffective under applicable law, such
-partial invalidity or ineffectiveness shall not invalidate the remainder
-of the License, and in such case Affirmer hereby affirms that he or she
-will not (i) exercise any of his or her remaining Copyright and Related
-Rights in the Work or (ii) assert any associated claims and causes of
-action with respect to the Work, in either case contrary to Affirmer's
-express Statement of Purpose.
-
-4. Limitations and Disclaimers.
-
- a. No trademark or patent rights held by Affirmer are waived, abandoned,
-    surrendered, licensed or otherwise affected by this document.
- b. Affirmer offers the Work as-is and makes no representations or
-    warranties of any kind concerning the Work, express, implied,
-    statutory or otherwise, including without limitation warranties of
-    title, merchantability, fitness for a particular purpose, non
-    infringement, or the absence of latent or other defects, accuracy, or
-    the present or absence of errors, whether or not discoverable, all to
-    the greatest extent permissible under applicable law.
- c. Affirmer disclaims responsibility for clearing rights of other persons
-    that may apply to the Work or any use thereof, including without
-    limitation any person's Copyright and Related Rights in the Work.
-    Further, Affirmer disclaims responsibility for obtaining any necessary
-    consents, permissions or other rights required for any use of the
-    Work.
- d. Affirmer understands and acknowledges that Creative Commons is not a
-    party to this document and has no duty or obligation with respect to
-    this CC0 or use of the Work.

 `BinaryType`
 :   container type to store arrays
 
-    Although not formally expressed as a C++ concept, `BinaryType` must be default-constructible,
-    copy/move-constructible, and support `push_back()`, `.data()`, and `.size()`, because
-    [`byte_container_with_subtype`](../byte_container_with_subtype/index.md) derives directly from it. Its
-    `value_type` must additionally be exactly one byte wide (e.g., `std::uint8_t`/`char`/`std::byte`): the binary
-    serializers (CBOR, MessagePack, BSON, UBJSON) read and write the container's raw bytes via
-    `reinterpret_cast`, which is only correct for byte-sized elements -- a container like
-    `#!cpp std::vector<std::intptr_t>` will not work as `BinaryType`. The elements must be stored contiguously, and
-    the binary readers additionally require `resize()` and `operator[]`. See
-    [Template Parameter Requirements](../../features/types/template_parameters.md#binarytype) for the full list.

 ## Notes
 
-### Default type
+#### Default type
 
 The default values for `BinaryType` is `#!cpp std::vector<std::uint8_t>`.
 
-### Supported byte types
-
-`#!cpp std::vector<std::uint8_t>`, `#!cpp std::vector<char>`, and `#!cpp std::vector<std::byte>` are supported.
-Regardless of which of them is configured, [`dump`](dump.md) writes the bytes as the numbers 0..255.
-
-### Custom BinaryType behavior
-
-When a custom `BinaryType` is configured (other than the default `#!cpp std::vector<std::uint8_t>`), you can assign
-values of that type directly to a `basic_json` instance, and they will automatically be recognized as binary values
-rather than arrays:
-
-```cpp
-using custom_json = nlohmann::ordered_json::with_binary_t<std::vector<std::byte>>;
-
-std::vector<std::byte> data{std::byte{1}, std::byte{2}, std::byte{3}};
-custom_json j = data;  // Creates a binary value, not an array
-assert(j.is_binary());
-
-// Round-tripping works seamlessly
-auto extracted = j.get<std::vector<std::byte>>();
-assert(extracted == data);
-```
-
-This automatic type detection is a convenience feature that only applies to custom (non-default) `BinaryType` configurations.
-The default `nlohmann::json` continues to treat `#!cpp std::vector<std::uint8_t>` as arrays for backward compatibility.

-!!! warning "Version-dependent effect on fmt"
-
-    `fmt` only picks up a `format_as` overload that returns a `std::string` in fmt **10.0.0 through
-    11.0.2**. Starting with fmt **11.1.0**, `fmt` restricts automatic `format_as` pickup to overloads that
-    return an arithmetic type, so this function has no effect there (it is simply unused, not a compile
-    error).
-
-    If you use fmt \>= 11.1.0, or want the same pretty-print spec support that
-    [`std::formatter<basic_json>`](std_formatter.md) has (`#!cpp "{:#}"`, a width to set the indent such
-    as `#!cpp "{:2}"`/`#!cpp "{:#2}"`, and fill-and-align to pick the indent character such as
-    `#!cpp "{:.>#}"`), define your own `fmt::formatter` specialization mirroring the same logic:
-
-    ```cpp
-    --8<-- "../../../tests/fmt_formatter/project/main.cpp:formatter_recipe"
-    ```
-
-    This recipe isn't shipped by the library itself, since doing so would make `fmt` a build dependency
-    (see the FAQ entry on
-    [using JSON values with `std::format` or `fmt`](../../home/faq.md#using-json-values-with-stdformat-or-fmt)
-    for more background) — but it *is* compiled and exercised against a real, current `fmt` release as
-    part of the library's own test suite (`tests/fmt_formatter`, via CMake `FetchContent`), so it's kept in
-    sync with `std::formatter<basic_json>` and verified to actually work, not just illustrative.

-2. Reads from an iterator range, or an iterator and a sentinel of a different type (C++20 ranges support).
-
-The exact mapping and its limitations are described on a [dedicated page](../../features/binary_formats/bon8.md).
-
-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - a container `obj` for which `begin(obj)` and `end(obj)` produce a valid pair of iterators
-      (as found via ADL or member functions, with semantics compatible to `std::begin` and `std::end`)
-
-`IteratorType`
-:   a compatible iterator type
-
-`SentinelType`
-:   defaults to `IteratorType`; may be a different type comparable to `IteratorType` via `operator!=`, for instance.
-
-    - a custom sentinel type for C++20 ranges
-    - `std::default_sentinel_t`, when `IteratorType` is `std::counted_iterator`
-
-## Parameters
-
-`i` (in)
-:   an input in BON8 format convertible to an input adapter
-
-`first` (in)
-:   iterator to the start of the input
-
-`last` (in)
-:   iterator to the end of the input, or a sentinel value that compares equal to the end iterator with `operator!=`
-
-`strict` (in)
-:   whether to expect the input to be consumed until EOF (`#!cpp true` by default)
-
-`allow_exceptions` (in)
-:   whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
-
-## Return value
-
-deserialized JSON value; in case of a parse error and `allow_exceptions` set to `#!cpp false`, the return value will be
-`value_t::discarded`. The latter can be checked with [`is_discarded`](is_discarded.md).
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Exceptions
-
-- Throws [parse_error.110](../../home/exceptions.md#jsonexceptionparse_error110) if the given input ends prematurely or
-  the end of the file was not reached when `strict` was set to true
-- Throws [parse_error.112](../../home/exceptions.md#jsonexceptionparse_error112) if a parse error occurs, for instance
-  an invalid byte, a string that is not valid UTF-8, or an object key that is not a string
-
-## Complexity
-
-Linear in the size of the input.
-
-## Examples
-
-??? example
-
-    The example shows the deserialization of a byte vector in BON8 format to a JSON value.
-     
-    ```cpp
-    --8<-- "examples/from_bon8.cpp"
-    ```
-    
-    Output:
-
