/*
  CoreShift CodeLabs premium visual system
  ----------------------------------------
  This is a static CSS system: no build tools, no frameworks, and no server dependency.

  Editing guide:
  - Brand colors live in :root.
  - Most cards use the shared glass-panel styling.
  - Motion uses transform/opacity for smoother performance.
  - Breakpoints are at 1024px, 820px, and 640px.
