/*
  Admin back-office (R13). Custom admin in plain Rails + Tailwind — NO Avo
  (explicit client decision). This file holds only the small set of structural
  hooks the back-office shell needs (fixed sidebar, scroll area, sidebar active
  state). Everything visual is Tailwind utilities in the views — zero inline CSS.
  Brand: gold accents on a clean neutral chrome (NOT the public premium navbar).
