   2026 EDITORIAL VISUAL SYSTEM
   Replaces the boxy "diagram made of cards" patterns with a
   unified editorial language:
     - signal-flow rails       (horizontal/vertical process rows)
     - layered architecture    (stacked tier bands, not card grids)
     - capability rows         (editorial feature rows)
     - status tokens           (elegant result markers)
     - dark-section surfaces   (charcoal rails instead of white tiles)
   These are reusable patterns. Legacy classes (.arch-diagram,
   .workflow-steps, .id-story, .process-flow, .flow-diagram) are
   restyled below to opt INTO the new system without requiring
   every HTML file to be rewritten.
