/* ScholarVera — shared styles
   Design direction: "the margin and the manuscript."
   The product is about the *process* of writing, so the visual language
   borrows from the manuscript page: a generous left margin rail (where an
   editor writes), a serif body for reading, a quiet ink-and-paper palette,
   and a single ink-blue accent. Restraint is the point — this is a trust
   artifact, not a sales page. */
