   a background of var(--ink) (light in dark mode) or a hardcoded #fff, paired with
   hardcoded white/light text — correct in light mode, but unreadable once dark mode makes
   the background light too. Their light/white backgrounds are kept as-is by design; only
   the text color needs to flip dark here. Only resting states need this: .btn-primary's
   hover (var(--ink-soft)) is also light in dark mode and needs the same fix, but
   .btn-outline's hover (var(--canvas)) is already dark in dark mode, where the existing
   light var(--ink) text is already correct — overriding it there would break it the
