   BigBell shared theme

   same colors, fonts, buttons, header and footer without duplicating the
   whole <style> block per template. Loaded globally via base.html, after
   style.css so it can override the old palette, and before each page's own
   extra_css block so a page can still add page-specific overrides on top.
