/* Project case studies, set like an MIT Media Lab article: a full-width cover,

   story as one column of plain text — headings, a bold italic lead, paragraphs,
   lists, quotes — and figures whose captions sit in the right margin. Neutral
   palette only; colour comes from the project imagery.

   Markup vocabulary (pages/projects/*.vue):
     header.project-header   .project-kicker, h1, p.lead, p.project-award,
                             p.project-links > a.btn
     dl.project-facts        div > dt + dd, one per fact
     section                 h2, p.lead, p, h3, ul/ol, blockquote,
                             p.statement, figure
     figure                  img / video / iframe (or div.figure-grid of them)
