   Cal renders an entire HTML page inside its iframe. The .main flex

   push to the bottom, expanding any white gap between the booker card
   and the bottom of the iframe.

   We can't reach inside the cross-origin iframe with CSS, so we have
   to drive everything via Cal's API. cssVarsPerTheme.dark sets every
   cal-bg-* variant dark (including speculative names like cal-bg-page,
   cal-bg-app, cal-bg-default) so whichever variable Cal's body uses
   internally, we've covered it. */
