/* Project Nehemiah — the organisation's home page (/).
 *
 * Its own look, separate from Guardian's (assets/site.css). It takes its cues from the
 * Project Nehemiah logo: crimson on parchment, engraved capitals, a dry-brush mark. The
 * grit borrows NCM's techniques (the New Creation Movement site), all made in code: a
 * photocopy grain over the whole page, brush-torn dividers, thick rules, square buttons
 * with a hard offset shadow. No texture images, so nothing to license and little to load.
 *
 * Fonts are self-hosted (the site's Content-Security-Policy allows no others):
 *   Cinzel       headings, the engraved capitals of the logo lockup   (SIL OFL 1.1)
 *   Newsreader   body text, NCM's serif                              (SIL OFL 1.1)
 *   Great Marker one hand-painted accent, from NCM                   (Apache 2.0; a
 *                derivative of Permanent Marker by Font Diner — see fonts/LICENSE-GreatMarker-*)
