/* DiffPixel reference pages (Manual / Privacy) — deliberately plain.
   Out of scope for the site's editorial/motion design system: these are
   task-focused documents, not a showcase. No drift-title, no scroll motion,
   no oversized display type, no decorative instrument blocks. base.css still
   supplies shared tokens, fonts, header, footer, and buttons. */
