text-ink uses --c-ink which is #012851 in light and #f0efe9 in dark, responding

bg-white is hardcoded #fff and only flips via the Tailwind dark: media-query variant.
bg-surface uses a CSS variable (--c-surface) that responds to both the media query
and the [data-theme='dark'] attribute, matching how all other cards on the page work.
