   Direction: museum weapons-catalog / engraved specimen plate — the same
   world as the marketing site (site-archive/marketing-v1-2026-09/), cut down
   to the rules this page uses. Values are copied verbatim; change them there
   and here together.
   No gradients, no glass, no drop-shadow cards — hairline rule, dimension
   line, and engraved linework are the only decoration this world permits.
