/* ==========================================================================
   Shared UI chrome
   --------------------------------------------------------------------------
   Components that appear on more than one page: the fixed KU header, the
   contact-form field helpers, and the collaborator filter control.

   These rules used to live in an inline <style> block in index.html. Any page
   that reused the same markup and JavaScript — /sund-collab renders results
   through the very same displayCollaboratorResults() — therefore rendered the
   header at the wrong width and the filter control completely unstyled
   (position: static, no background, browser-default button chrome).

   Keep genuinely page-specific styling in the page. Anything driven by shared
   markup in script.js belongs here, so a second page cannot silently miss it.
