Package: a11yviz 0.1.8

a11yviz: Accessibility Toolkit for 'ggplot2', 'plotly', and 'Quarto'

Makes charts and documents accessible across 'ggplot2', 'plotly', and 'Quarto', aligned with the Web Content Accessibility Guidelines (WCAG 2.1, <https://www.w3.org/TR/WCAG21/>). Includes WCAG-tagged palettes, alt-text scaffolds, audits, a document rubric, heading and reading-level checks, 'shiny' ARIA helpers, and a stylesheet for 'DT' and 'DiagrammeR', as employed in Shin et al. (2026) <doi:10.1177/07319487251412879>.
