/* ── S&T Nav — Shared Primitives ──────────────────────────────────────────
   Imported by ALL Cloud Run embedded pages (dashboard and public alike).
   Contains only structural/visual primitives — no state-specific classes.
   Auth note: Memberstack v2 session key is ms_session_id (verified in devtools 2026-03-16).
   Not _ms-mem — that key does not exist. Verify in devtools if Memberstack is upgraded.
