- Make the iterator range illustrations legible in dark mode (prefers-color-scheme
rules inside the SVGs).
- Add a "Byte layout" section with a color-coded byte table to each binary format
page (BJData, BON8, BSON, CBOR, MessagePack, UBJSON), and highlight the smallest
size per file in the comparison table.
- Add "See also" sections to the overview pages that lacked one.
- Split the release notes into one page per release, grouped by minor version on
the overview page, with an "API changes" section per release generated from the
API pages' version histories (hooks/api_changes.py).
- Fact-check the release notes and version histories against the release tags and
correct wrong or misleading entries (e.g., json_serializer 2.1.0, merge_patch
3.1.0, items, count, operator[], to_bjdata, std::string_view key support).

* Fix math formulas rendering as raw TeX in the published docs
The privacy plugin self-hosts MathJax 2.7.0 but drops its
?config=TeX-MML-AM_CHTML query string, so the rehosted script loads no
input jax and the 10 formulas across 6 pages render as raw TeX to
readers. Remove pymdownx.arithmatex and the MathJax extra_javascript
entry, and rewrite the formulas in plain HTML (<sup>, <i>) instead.
This also drops a nine-year-old third-party script from every page.

* Fix publish_documentation triggers and persist unneeded git credentials
publish_documentation.yml only triggered on docs/mkdocs/** pushes, but
the site also embeds .github/CODE_OF_CONDUCT.md, CONTRIBUTING.md,
SECURITY.md, cmake/{clang,gcc}_flags.cmake, .clang-tidy,
tools/astyle/.astylerc and tests/fmt_formatter/project/main.cpp via
pymdownx.snippets, so changes to those files never republished the
site. Extend the path filter to cover them, and switch runs-on from
the long-pinned ubuntu-22.04 to ubuntu-latest to match
ci_test_documentation.
Also add persist-credentials: false to the checkouts in ci_icpx and
ci_nvhpc (ubuntu.yml) and msvc-vs2026/msvc-arm64 (windows.yml), none
of which pushes with git, matching every other checkout in these
workflows.

* Fix example build: broken debug echo, deprecations hidden for everything
docs/Makefile's debug echo used a space instead of a comma in
$(call cxx_standard ...), so it always printed an empty standard.
Every example was also compiled with -Wno-deprecated-declarations,
which would silently hide an accidental deprecated-API call in any of
them. Factor the duplicated compile flags into EXAMPLE_CPPFLAGS/
EXAMPLE_WARNFLAGS, build with -Werror=deprecated-declarations by
default, and only allow the three examples that intentionally
document deprecated API (the DEPRECATED_EXAMPLES list) to suppress it.

* Fix check_structure.py NOLINT parsing and an off-by-one report line
`line.strip("<!-- NOLINT")` followed by `.strip(" -->")` strips any of
the characters in those sets from both ends, not a literal prefix; it
only happened to work for "Examples". A NOLINT'd section name
starting with N, O, L, I or T (e.g. "Notes", "Template parameters",
"Iterator invalidation", "Literals") was silently mangled, so the
suppression did not apply and the checker could report a spurious
missing/misordered section. Parse the comment with a regex instead.
The same fragile strip() pattern was used for heading text; replace it
with a plain prefix slice. Also fix the admonition_title report, which
used the 0-based line index while every other report in the file uses
lineno+1.

* Fix docset README's non-existent make target and stale fallback URL
The README told readers to run `make nlohmann_json.docset`, but the
Makefile's targets are `all`, `JSON_for_Modern_C++.docset` and
`install_docset_zeal`; the documented command has failed with "No
rule to make target" since #2967 (2021). Point the README at the real
target and folder name. Info.plist's DashDocSetFallbackURL also still
pointed at the old nlohmann.github.io/json/ URL instead of the
canonical https://json.nlohmann.me/ from mkdocs.yml's site_url.
Leave list_missing_pages/list_removed_paths alone: they may become
redundant once #5638's check_docset() lands, which is a follow-up.

* Fix MacPorts CMake example to include its own snippet files
The MacPorts "Example: CMake" block included
integration/homebrew/example.cpp and
integration/homebrew/CMakeLists.txt instead of the MacPorts files
right next to it, a copy-paste slip from the Homebrew section. Nothing
referenced integration/macports/CMakeLists.txt as a result. The page
rendered correctly only because the homebrew, macports and
vcpkg/CMakeLists.txt snippets are byte-identical, so a future edit to
the MacPorts files would not have shown up on the page.

* Do not persist git credentials in publish_documentation's checkout
The checkout step in publish_documentation.yml left the default
persist-credentials: true, so GITHUB_TOKEN stayed writable in
.git/config for the rest of the job (zizmor's artipacked finding). The
Deploy documentation step authenticates through its own github_token
input to peaceiris/actions-gh-pages and does not push with the
checked-out credentials, so persist-credentials: false is safe here,
matching every other checkout in the workflow set.
Overlaps #5638, which edits this same checkout step (adds
fetch-depth: 0); expect a rebase conflict there.

* Replace list_missing_pages/list_removed_paths with a comm(1)-based diff
The docset Makefile's list_missing_pages ran one sqlite3 query per
mkdocs page, and list_removed_paths nested a loop over all mkdocs pages
inside a loop over all docset index paths (O(n*m) shell iteration).
Issue #5718 item 5 suggested removing or reducing these targets once
#5638's check_docset() lands, but that PR is still open and covers only
API pages and macros, not the full page set these targets check.
Replace the loops with two sorted path lists (DOCSET_PAGE_PATHS from
mkdocs' markdown sources, DOCSET_INDEX_PATHS from the built docset
index) compared with a single comm(1) call each, verified to produce
output identical to the old loops against the current docSet.dsidx.
The sed expression used '#' as its delimiter, which GNU Make reads as
a comment character even inside a variable assignment, truncating the
line and orphaning the closing paren of $(shell ...) ("unterminated
call to function 'shell': missing ')'"). Use '@' as the delimiter
instead.

* Add BON8 support
Add to_bon8/from_bon8 and input_format_t::bon8 for BON8, a binary format
that uses the byte values that cannot begin a UTF-8 character as type
markers, so strings need no length prefix. It is the most compact of the
supported binary formats on the benchmark files.
The reader is non-recursive like the other binary readers. A string ends
at the first byte that cannot continue it, so the reader hands the one or
two bytes it reads past a string back to the value that follows. The
writer produces the canonical representation of the specification, except
for NFC normalization; its output is identical to that of the reference
implementation (HikoGUI) on all files of the test data.
The round-trip tests need the .bon8 files of json_test_data 3.2.0.

* Address review comments
- Reuse detail::validate_one_utf8 to check strings in to_bon8; the error
now names the first byte of the invalid sequence.
- Document that to_bon8 leaves bytes in the output adapter on an
exception, and that string_open is only an output of write_bon8_marker.
- Explain why the pushback buffer of the BON8 reader cannot overflow.

* Read BON8 strings in bulk from contiguous input
- copy the valid UTF-8 of a string in one step when the input is
contiguous (twitter.json is read in 1.68 instead of 2.52 ms,
jeopardy.json in 196 instead of 297 ms, close to CBOR and MessagePack)
- share the new valid_utf8_prefix() with the writer's UTF-8 check, which
now skips ASCII 8 bytes at a time
- let the fuzzer check that contiguous and stream input give the same
value or error, and test both paths in the unit tests
- clarify that a second 0xFF after a string is an empty string

* Read BSON keys in bulk from contiguous input
BSON keys (and array indices) are C-style strings, which were read byte
by byte. For contiguous input they are now read up to their \x00-byte in
one step, using the same bulk_scan flag as BON8 strings: twitter.json is
read in 1.46 instead of 2.01 ms, citm_catalog.json in 2.93 instead of
3.33 ms, jeopardy.json in 182 instead of 207 ms. canada.json, whose keys
are almost all one-digit array indices, takes 2 % longer.

* Fix the BON8 CI failures of the bulk-read tests
- skip the contiguous-versus-stream tests of BON8 strings and BSON keys

* Move the explicit basic_json instantiation into its own test file
Linking test-regression3_cpp20 with clang and MinGW failed with
"relocation truncated to fit: IMAGE_REL_AMD64_REL32 against `.rdata'",
as test-regression2 did before #5511. The explicit instantiation of
basic_json<> for #4825 compiles every member function, including the
BON8 reader and writer, into that object, and it was already close to
the limit (2,226,104 bytes on develop, 2,234,960 with BON8; clang -O1,
C++20).
Give the instantiation a file of its own: unit-regression3 is now
1,594,736 bytes and unit-explicit_instantiation 1,095,064. The new file
mentions JSON_HAS_CPP_17 and JSON_HAS_CPP_20 so it keeps being built
for the C++17 standard the regression was about.

* Convert the bytes of the BON8 test strings explicitly
The str() helper constructed a std::string from a byte range, which
