Subject: [PATCH 01/21] Seed _axe-baseline.json with the one carried-forward
 entry

Re-checked all 27 entries from the old harness baseline
(origin/feat/axe-a11y-harness:_tools/axe/baseline.json) against the
2026-09-15 quarto-web 1.11.4 scan. Only scrollable-region-focusable ::
#cb still has both a live signature and a note that still holds
(quarto-cli#14378, still open). Three entries were fixed upstream
(#14615, #14376) and no longer appear. The remaining 23 carried empty
notes with no recorded reasoning, so they're held open for a fresh
re-triage (accessibility repo strand ax-xmy5f5qm) rather than carried
forward blind.

Subject: [PATCH 02/21] Accept the dygraphs axis-label contrast on the
 htmlwidgets page

dygraph.js sets the axis-label color with an inline style, so no CSS can
override it. dygraph.js >= 2.0 moves it into a stylesheet rule, but the R
dygraphs package still bundles 1.1.1 (rstudio/dygraphs#241). Scoped to
htmlwidgets.html: the same signature on penguins-preview.html is a real
Quarto defect that must stay visible.

Subject: [PATCH 03/21] Accept the Observable Plot g[aria-label] findings as
 third-party

Plot puts an aria-label with no role on the <g> of every mark and axis.
20 signatures in two groups:

- 10 axis-tick and grid signatures are fixed in Plot 0.6.14
  (observablehq/plot#2018). Quarto bundles Plot 0.6.11, so these wait on
  quarto-cli#14934. Prune them when Quarto updates Plot.
- 10 data-mark signatures still occur in Plot 0.6.17. Plot labels marks
  on purpose (observablehq/plot#944); the open request for a role is
  observablehq/plot#1760.

Subject: [PATCH 04/21] Accept the Observable Inputs unlabeled slider and
 checkbox findings as third-party

Inputs.range puts its <label for> on the number box only, so the slider
has no accessible name even when `label` is set. Inputs.table row and
header checkboxes have no label, and no option adds one. Inputs 0.12.0
has the same markup, and no upstream issue reports either defect.

The two .oi-3a86ea-input signatures are site-wide; the selector becomes
.inputs-3a86ea-input when Quarto updates Inputs (quarto-cli#14934). The
four generic signatures are scoped to their pages, so a new unlabeled
input elsewhere still shows as new.

the broader p > .img-fluid signature also covers real content images on
other pages that still need alt text of their own.

Subject: [PATCH 08/21] Accept the leaflet marker-icon and attribution findings
 as third-party
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

leaflet.js sets role="button" and tabindex="0" on marker icons that also
carry alt="" (implicit presentation role), and its attribution control's
CSS isn't dark-mode aware. 7 signatures / 9 marker instances + 2 contrast
findings (2 instances each) across docs/interactive/index,
docs/interactive/widgets/{htmlwidgets,jupyter}, the revealjs demo, and the
three leaflet maps on docs/authoring/article-layout. No upstream issue —
this is leaflet's own markup and CSS, not Quarto's.

Subject: [PATCH 09/21] Accept the knitr::kable() and Arquero table findings as
 third-party

knitr::kable() leaves the row-name corner cell as an empty <th> by
design, not oversight: yihui/knitr#1747, merged as PR #2500 on
2026-09-19, added scope="col"/scope="row" to kable's other header cells
but explicitly kept the corner cell blank and unscoped. 5 signatures / 7
instances across notebook-embed, penguins(-preview), three kable()
examples on article-layout, and the revealjs demo's Data tab.

Arquero's table viewer hardcodes background: #fff via inline JS style, so
its sticky header text fails contrast in dark mode (1 signature, 22
instances, reused on both the arquero example and libraries pages).

Each of the 5 kable entries repeats the full note, so the context
survives if any one entry is pruned.

Subject: [PATCH 10/21] Accept the code-preview frame-title findings as

The 35 code-preview iframes have no title (quarto-cli#14770). They clear
when quarto-cli#14933 ships, because fix/code-preview-titles already sets
code-preview-title on every preview.
