Original description below:

What's the task?

Should we setup pa11y-ci https://github.com/pa11y/pa11y-ci for this project:

• possible defaults in .pa11yci.json:

  "defaults": {
    "timeout": 240000,
    "runners": ["axe"],
    "ignore": ["color-contrast"],
    "concurrency": 1,
    "chromeLaunchConfig": {
      "ignoreHTTPSErrors": true,
      "args": ["--disable-dev-shm-usage", "--no-sandbox"]
    }
  },

• some projects use a sitemap for the urls but we might need to finesse a possible url export of the data to get it into a format pa11y likes
