   The non-obvious part is that the HERO h1 and the SECTION h1s differ:
     hero h1     32px / 700 / white          (bold, full strength)
     section h1  32px / 300 / 0.56 or 0.54   (light AND dimmed)
   Getting that backwards — bold, full-opacity section headings — is what
   made the earlier pass read as "not Material" even with the right font. */
