Review comments at @themes/claude.json:
- Around line 25-26: Update the accentForeground values in both variants of the
theme configuration to use a dark foreground that meets WCAG AA contrast for
normal-sized text against the clay accent. Preserve the existing accent color.
- Around line 80-81: Darken the textMuted color in the light variant of the
claude theme so it meets WCAG AA’s 4.5:1 contrast requirement against #fcfcfb
and #ffffff. Change only the textMuted value; preserve the other theme colors.

Use a dark foreground for the clay accent.
accentForeground is used for normal-sized text in controls such as CopyJsonButton and the header. In both variants, #ffffff on #d97757 provides only about 3.1:1 contrast, below the 4.5:1 WCAG AA minimum. Icon-only and large-text uses are not covered by this threshold.

Darken textMuted in the light variant.
textMuted styles normal-sized descriptions, navigation, headings, and list text through text-ink-muted. #898781 has only 3.5:1 contrast on #fcfcfb and 3.6:1 on #ffffff, below the WCAG AA minimum of 4.5:1. Use a darker muted text color.
