/*
===============================================
New header / footer chrome

This stylesheet styles the shared header, signed-in subheader (tab
strip) and footer that render on EVERY page via _Layout.cshtml - both
the redesigned pages and the legacy pages that still use the old
style.css/mobile.css for their own content below the nav.

It is deliberately scoped to the <header>, <nav class="subheader"> and
<footer> elements (and a couple of classes that only ever appear
inside them: .badge, .burger, .navlink, .brand, .logo). It must never
style bare tags/classes that legacy page content also uses (button,
.badge, .row, .column, h1/h2, section, main, etc.) - that CSS lives in
experian.css instead, and is only loaded by the pages that were
actually redesigned.

The header and signed-in subheader are fixed/sticky on every page, so
they stay visible while scrolling. Since that takes them out of normal
document flow, this file also adds a matching top padding to <body> so
legacy page content isn't hidden underneath them. Redesigned/hero pages
(that also load experian.css) cancel that padding, because their hero
section is designed to run behind the transparent header instead - see
the "Hero header" section at the top of experian.css.
