/* ISOGRID shared chrome — the header, footer and typefaces every page
   other than the homepage uses (product pages, checkout, order pages,
   legal pages, 404). The homepage keeps its own patch-bay header inline;
   the values here mirror its mobile nav, cart button and footer, so if
   those change in production_index.html, change them here too.

   Typeface roles (same as the homepage):
     Oxanium       headings
     Space Mono    body copy, labels, buttons   (loaded from Google Fonts
                                                  by each page's <head>)
     Vibrocentric  spec values, lists, footer */
