+### Fixed
+
+- **The JavaScript render harness installs again on the Ubuntu 26.04 runner
+  image.** GitHub moved `ubuntu-latest` to Ubuntu 26.04, and Playwright 1.55.1
+  refused to install Chromium there, so every `impl-generate` and `impl-repair`
+  run for Chart.js, D3, ECharts, Highcharts and MUI X failed in its setup step.
+  Playwright moves to 1.64.1, which knows the new image and brings Chromium 156
+  instead of 140; a sample of 17 catalogue snippets in both themes renders
+  pixel-identical to the 1.55.1 renders. (#12259)
