/* shared.css — header, nav, buttons, footer.
   Used by every page (index.html, help.html, about.html, contact.html, etc).
   Edit this ONE file to restyle the header/footer everywhere — don't copy
   these rules into individual pages' own <style> blocks.
   Each page still defines its own :root color variables before this loads;
   that's fine, they're just brand constants and won't drift in practice. */
