/* DelphiCall Customer UI – global theme */

/*
  Purpose
  -------
  Global base theme and shared design tokens for the Customer UI.

  Responsibilities
  ----------------
  - Define light and dark theme tokens
  - Provide shared typography, spacing and surface styles
  - Supply reusable button, form, table and card base styles

  Theme rules
  -----------
  - Use tokens instead of hardcoded UI colors
  - All new component CSS should build on these variables
  - html[data-theme="light"] and html[data-theme="dark"] are both supported
