   The brand is an engineering mark, so things should look BUILT rather than

     1. the rule is drawn        (a line scales out from the leading edge)
     2. the frame is wiped in    (clip-path opens like a plotter pass)
     3. the content settles      (a short rise into the frame just made)

   Beats are ordered by delay, not by chaining, so a dropped frame cannot
   leave a piece half-built. Everything is transform/opacity/clip-path —
   no layout is touched while the page scrolls.

   All of it hangs off `.armed`, so an element only animates once JS has
   taken responsibility for revealing it. */
