/* Name Game website.
   Colors and spacing mirror name-game-app/src/constants/theme.ts.
   --text-muted and --link are adjusted from the app's textSecondary /
   accentSecondary so body text passes WCAG AA on every surface: the app's
   #7A7268 passes on the page background but not on --surface, where the
   steps and cards put secondary text. Amber is a fill only; text and focus
   rings on cream use terracotta or ink. */
