/* Ensure high contrast for all text against backgrounds (AAA where possible)
   - Text (#1A1A1A) on White (#FFFFFF) is excellent.
   - White (#FFFFFF) on Dark Blue (#0033A0) is excellent.
   - White (#FFFFFF) on Red (#D90429) is excellent.
   - Red (#D90429) on White (#FFFFFF) for links/text needs checking (Likely AA, might need to darken for AAA on small text if red text is used).
     For buttons with red background and white text, this is fine.
   - Dark Blue (#0033A0) on White (#FFFFFF) for headings is excellent.
