/* Burichang Salafiah Madrasha: the one stylesheet every public page shares.

   Change the look here, once, and every page follows:
     1. Colours, fonts, widths           (:root, below)
     2. Header, menu drawer, phone bar, footer
     3. Shared page parts                 (page banner, section titles, dividers)
     4. Language: Bengali / Arabic        (.lang-bn, .lang-ar)
     5. Motion                            (.reveal)

   A page's own layout (only what that page has) lives in Styles/pages/<page>.css,
   loaded after this file by partials/site_head.php. Nothing is repeated between files. */
