On mobile, body already has padding-top:60px to clear the fixed header, but
every page ALSO added its own clearance — doubling it and leaving a ~60px
white gap under the menu (content sat too low). Trimmed each page's mobile
top offset so it relies on the body padding (matching .article-page, which
was already correct): page-content, support/hub/legal pages, and the
news-hub / news-article / blog / member heroes. Content now sits ~32-42px
under the header.
Also add a 32px top gap to .newsletter-cta on mobile so it no longer
touches the CTA/content above it.
CSS only.
