/* Deliberately NOT "position: relative" here, matching production exactly
   (confirmed via getBoundingClientRect on the live site): a Phase 3b fix
   had added it, to give ".menu-toggle-button--site-search" (the search
   icon, below) a stable positioning context so its "position: absolute"
   rule wouldn't resolve all the way up to ".header" -- whose height
   varies with menu-toggle/sticky state, making the icon visibly "jump up"
   on scroll. Found via a user report that the site search box itself was
   broken: giving .main-search its own positioning context ALSO made it
   the containing block for ".main-search__block-wrapper" (the search
   panel, a sibling descendant of .menu-toggle-button--site-search), which
   relies on ".header" being its containing block for TWO things at once
   -- spanning the full page width via "left: 0; right: 0", AND landing
   directly below ".name-tag" via "top: 100%" (.header's rendered height
   includes both .business-nav and .name-tag; .main-search's narrow
   ~72px-wide box does not). Reverting to plain parity with production
   here undoes the Phase 3b icon-stability fix in exchange for fixing the
   more severely broken, user-facing search panel; re-fixing the icon's
   scroll-jump without reintroducing this regression needs a mechanism
   that doesn't change the search panel's containing block too (e.g. a
   JS-computed position, matching how sticky-nav.js already computes
   --sticky-nav-height/--sticky-header-height dynamically for a related
   problem) -- out of scope for this fix. */

/* Found via a user report that the search box was invisible once opened
   on a scrolled/sticky page: "top: 100%" above is relative to this
   element's OWN containing block, which is .main-search normally (no
   position set, so resolution continues up to .header) -- but once
   ".business-nav.sticky" (an ancestor, between .main-search and .header)
   becomes "position: fixed", IT becomes the nearest positioned ancestor
   instead (position:fixed always establishes a valid containing block),
   so "top: 100%" now means 100% of .business-nav's own height alone
   (measured/published as --sticky-nav-height by js/sticky-nav.js), NOT
   .business-nav plus .name-tag combined (--sticky-header-height, which
   .innerpage-nav.sticky's own "top" below already correctly uses for the
   same reason). Since .name-tag also independently becomes
   "position: fixed" when sticky, sitting immediately after
   .business-nav using its OWN "top" offset, the search panel and
   .name-tag ended up occupying the exact same ~41px band whenever both
   were sticky -- with .name-tag (compared directly against this
   deeply-negative z-index panel, since fixed elements with z-index:auto
   don't create their own stacking context) painting over the entire
   search input. Overriding "top" here to the combined height once
   .business-nav is sticky makes the panel open directly below .name-tag
   instead, matching the non-sticky behavior (where .header, the
   correctly-resolved containing block there, already includes
   .name-tag's height naturally). */
