/* -------------------------------------------------------------------------
   HEADER — collapse to a clean single-row bar (brand left, hamburger right).
   Two things have to be beaten here:
   1. WP core stacks columns on mobile by default via
      `.wp-block-columns:not(.is-not-stacked-on-mobile) > .wp-block-column`
      (specificity 0,3,0, !important). Our selectors use 4 classes (0,4,0) so
      they win regardless of stylesheet load order.
   2. The nav column's `flex-basis:auto` base size mis-resolves to the full row
      width (its only in-flow child is the hamburger, yet auto-sizing balloons),
      which collapsed the brand to 0 and pushed the hamburger off-screen. Giving
      the nav column an explicit fixed basis sidesteps that entirely.
   The WP hamburger itself is forced on at <=999px by legacy rules in style.css.
