   2. Mono means measured: .m on data figures with a checkable basis and
      .cite on citations. Sentence case, zero tracking, never on labels.
   3. Red accent WORDS carry the purpose only (democratize / never /
      democratized). Red marks = Stimpod data and the 80%.
   4. One filled button per section; everything else is a .tlink.
