/* Integration Charter.
   Bordered-frame spec-sheet that pairs with how-it-works-pivot + the
   sovereign-charter vocabulary: L-brackets, tinted frame, white inner
   table, mono labels. Five rows, three columns:
     [Layer number + name]  |  [Named partner pills]  |  [Integration role]
   Below the table, two compact tag strips carry Silicon + Cloud
   burst targets as named support claims without taking charter rows. */
