/* ── Page headline ──
   ONE type scale for every page's h1. It used to be ten hand-written rules: the
   five concept pages each carried a byte-identical copy of one override, and
   about / partners / demo / vs-quickbooks / beta each carried their own near-copy
   that had drifted to 44 / 44 / 46 / 46px on the desktop and 31 / 32 / 33px on a
   phone — differences nobody chose, arrived at by copying the page next door and
   nudging a number.

   Two colour shapes, both declared HERE rather than per page: solid amber (the
   default, the round-3 brand decision), and `.h-display--duo`, a cream headline
   whose closing phrase is amber. The gradient on that phrase was one of three
   different hand-rolled versions; this is the one from /partners/.

   The legal set is deliberately NOT on this scale — those pages render through
   legal.css as documents, not heroes. */
