   The calculator is embedded in an iframe on curbwaste.com, which is a light

   inside a light article — so the palette above is the only palette. Depth and
   contrast come from the navy focal panels (hero, SAFER band, multiplier,
   next-steps), not from a second theme.

   `color-scheme: light` also stops browsers auto-inverting form controls. */
