   HANDSHAKE — Surfaces system
   One brand, two surfaces:
     .surface-admin  → Console: light lander palette, green + purple accents
     .surface-user   → Studio:  light, calm, friendly
   Shared DNA: Aquamarine signal, Inter, pill geometry, chips.

   Load Inter / Roboto Mono via <link> in page heads (not @import) —
   stalled Google Fonts @imports can block the rest of this stylesheet
