   Structural motif: the identity mark is built from load-bearing
   rectangular forms (beam / support / beam / support). That logic
   carries into layout: sections are marked by a single "beam" —
   a short, deliberately-sized horizontal bar whose width signals
   weight, not a decorative hairline repeated everywhere.
