/* =========================================================================
   composed-services-band.css — /technology §3d · v1.0 (2026-05-03).

   Locked structure:
   · CONTINUATION SURFACE from §3a — gold left rule continues, same cream
     surface (--ws-page), no new eyebrow. §3 is one Architecture act.
   · Three control-dimension chips above (PPN · EPN · QPCN) — typology row.
   · One functionality-dimension chip below (EasyAccess Authorization) as
     a smaller horizontal connective-tissue band — three nouns above, one
     verb below.
   · NO connector glyph. Mono caption only.
   · Role-captions, not definitions. Parallel grammar.

   Each chip is a peer in its row; chips do NOT carry sub-network
   detail. PDN/PAN/PAI sub-structure is unpacked in body prose elsewhere.
