/* ============================================================
   TAIGL WEBSITE — SCOUT INSTRUMENT SURFACE (WEB-018)
   Scoped presentation layer for the Scout product surface.

   Purpose: represent the REAL current Scout Android experience
   (Founder-approved visual direction, Platform Issue #940,
   render authority 2a39ce2030a11a4efdfb374dd7d7f28643d416b9)
   inside the existing frozen "Open Register" website system.

   This is NOT a website redesign and NOT a Scout redesign.
   Every rule here is namespaced under .sci- / .scout-device so
   no existing Open Register component changes behaviour.

   Frozen Scout visual principles honoured:
   - Inter-led product typography; no serif in the device frame
   - TAIGL dark environment + Horizon/Radar/Scout violet lineage
   - Cyan reserved for operational/action signal
   - Semantic green/amber retain governed meaning
   - One-screen mobile-first composition, progressive workflow
   - Reticle / signal-acquisition instrumentation grammar
   - RECEIVE intelligence spine with aligned semantic nodes
