   systems-register.css — Three-lens Systems Register
   ============================================================
   Ported verbatim from the 6-5-2026 design handoff
   (_extracted_pib_design/systems.css), with class names
   preserved so the Razor markup matches the prototype.

   Inherits foundational tokens from portal.css:
     --ink, --ink-2/3/4, --rule, --rule-2, --paper, --paper-2,
     --white, --shadow-1/2, --green, --green-bg, --teal,
     --teal-bg, --gold, --gold-bg, --vis-public/internal/restricted

   Adds indigo Systems accent + classification vocabulary, register
   tables, filter toolbar, and the detail page chrome.
