/* Layout: one 64ch reading column on grained paper; two static paper objects break out to 860px:
   a maintenance ticket beside a connection receipt, each with its acceptance question (Figure 1)
   and a compatibility matrix on taped graph paper (Figure 2).
   Gold = provider-side completion; blue = client-side interoperability.
   Every rule below is scoped to its figure so none of it can restyle the generated Read next block.
   Labels stay at 11px or larger. */
