   DARK THEME
   Everything is driven by CSS custom properties, so the dark variant is
   mostly a remap of the tokens, plus a handful of overrides for elements that
   use the strong navy as a *fill* (buttons, active pills) and need white text
   on a solid accent rather than dark text on a now-light token.
