/* ═══════════════════════════════════════════════════════════════════════════
   OSMOS ONE — shared brand surface for the assessment tool.

   Ported from osmos-ai (app/src/client/styles/tokens.css + Main.css):
   violet primary, green success, #0A0E16 canvas, Plus Jakarta Sans / Michroma,
   glass-morphism auth card. Loaded by both login.html and index.html so the
   public login page and the gated tool share one identity.

   Also defines the CONFIDENTIAL treatment (top bar + footer) required on every
   page of this commercial-team tool.
