/* ============================================================
   v3 pages/features.css: Features (prototype features.html).
   The list is server-rendered in production; script only filters it.

   Class map from the prototype (ft- to rt-feat-):
     ft-find, ft-count, ft-sub     rt-feat-find, rt-feat-count, rt-feat-sub
     ft-rail                       rt-feat-rail (buttons use aria-pressed)
     ft-group, ft-group.dark       rt-feat-group, rt-feat-group-dark
     ft-gh, ft-grid, ft-card       rt-feat-gh, rt-feat-grid, rt-feat-card
     ft-new, ft-none               rt-feat-new, rt-feat-none
   The even-row tint relies on the groups being sibling <section>s.
