TYPO3 Accessibility Skill

WCAG 2.1 Level AA compliance standards for TYPO3 v13 and v14.3 LTS sitepackage frontend development.

v14 a11y wins (use as reference):

• Camino theme (v14.1+, Feature #108539) is an alternative to bootstrap-package with configurable nav/footer — validate a11y when opting in.
