/* =====================================================================
   SYNAPSE.EXE DESIGN SYSTEM -- shared tokens and page shells.

   Every colour here was sampled from the brand reference image (deep royal
   blue, electric-cyan glow, and the green / orange / amber / sky badges).
   The reference implementation of every screen lives in
   tools/design-preview/preview.src.html -- open tools/design-preview/index.html
   to see it.

   Two modes share one palette. A page opts in with a class on <body>:

     body.mode-clinician  screens a clinician uses alone: sign-in, PIN, Client
                          Portal, Schedule, Data Entry, Progress Monitoring,
                          Record, Settings. Cool-mist background, white cards,
                          flat controls, ONE action colour (orange).
     body.mode-play       the activity hubs a child plays from: Game Hub,
                          Articulation, Language, Flashcards, Puzzles, Social
                          Skills. Deep-blue neural backdrop, glass cards,
                          glowing badges, big rounded playful buttons.

   The older --app-* names are kept as aliases of the new palette, so any
   stylesheet that still reads var(--app-*) picks up the new look. New code
   should prefer the --sx-* names below.
