/* Privacy Architecture whitepaper — a marketing-flavored trust page in the legal
   family. Builds on legal.css (nav, wrap, term, grid-bg, type, the [data-lang]
   toggle) and adds the whitepaper's own components. The brand fluorescent lime
   (#baff00, from the OKEight mark) is spent ONLY on the positive "on-device /
   your control" moments; everything else stays as quiet as the legal pages. */
