All ~100 Ubuntu jobs ran on every push to every pull request. They now
belong to three sets, chosen by each job's if: condition:
- PR set (16 configurations): every push to a pull request and every
push. Together with the checks that always run, these jobs would
have caught at least 92 % of the failing commits of Sep/Oct 2026.
- full set (73 configurations): after the PR set passed, on pushes and
on pull requests with the "🚀 ready to merge" label.
- nightly set (10 configurations): Infer, Valgrind, coverage, icpc,
icpx, nvhpc, CUDA, and ARM64; nightly on develop, on pushes to master
and release/*, and by hand. A failed nightly run opens or updates an
issue.
A matrix whose entries belong to different sets is split into one job
per set; the jobs share their steps through YAML anchors. No
configuration is removed: tools/ci_jobs/ci_jobs.py --compare lists 150
configurations before and after. The same tool checks in CI that every
job belongs to exactly one set, that the full set waits for the whole
PR set, and that the job table in quality_assurance.md is up to date.
The documentation describes the sets in a new section "How CI runs",
and the QA pipeline figure shows the new badges.

* docs: new design for the documentation site
Apply the brand to the Material for MkDocs site: Inter and JetBrains Mono
served by the site (upright and real italic), brand colours, blue header band
with the syntax pattern, wordmark in the header, new home page (hero, cards,
animated feature tour), 404 page, polish for tabs, search, footer, focus
rings, tables and code blocks, and theme features (code copy, previous/next
footer, TOC follow, search suggestions).
Draw the number railroad diagram, the parser callback events and the iterator
illustrations as inline SVGs that follow the light and dark scheme. The
generator scripts are in docs/mkdocs/scripts/figures; the feature slideshow
(json-light.svg, json-dark.svg, replacing json.gif on the home page) is built
by docs/mkdocs/scripts/slideshow. Decision nodes in five flowcharts become
hexagons, which need far less room.

* docs: add figures, table captions and a macro chooser
- Figures with numbered captions: SAX stepper, json_view layout and edit
stepper, exception map, JSON pointer and patch walkers, QA pipeline,
scaling and binary size charts, roadmap lanes, release timeline,
integration decision tree and namespace builder
- Table captions (nj-table-caption) on 9 pages
- Compile times: modules and PCH charts, filesystem section, re-measured
Figure 1, links between features/modules.md and compile_times.md
- Interactive macro chooser for features/arbitrary_types.md
- Link check: exclude URLs that answer the plugin with 400/401/419 or are
dead (customers.md)

* docs: macro chooser generates adl_serializer for non-default-constructible types
Signed-off-by: Niels Lohmann <mail@nlohmann.me>
* docs: cross-link concept pages and API pages in See also sections
Add See also links in both directions between the concept pages (features,
home, integration) and the API pages, write API links in code font, give every
entry a comment after a dash, and show the callback event figure on the parser
callbacks page.

* docs: address review comments on the new design
- Home: add a "Latest release" button
- Sponsors: update the list and group it by tier
- Features: list all feature pages on the index page
- Releases: add highlights per release, link the 4.0 roadmap, add the first commit to the timeline
- Exceptions: prefix all example messages with the exception name
- API: no code font for format names in the See also links of the to_/from_ pages
- Merge Patch: show the document before, the patch, and the result
- Replace "--" with typographic dashes, mark external links with an icon, center Mermaid diagrams
