   SOUTH EAST AVIATION HERITAGE NETWORK — SHARED SITE STYLES
   Used by every page (header, menu bar, search, footer, resets).
   Edit this file directly — every page links to it, so a change
   here updates the whole site immediately, with no rebuild step.
   Page-specific styling (hero, member list, venue page, etc.)
   lives in each page's own <style> block, not here.
