/* ==========================================================================
   Design Tokens: THEME VARIABLES
   ==========================================================================
   This block defines the visual design language of the application.
   It's structured in three layers for maximum clarity and maintainability:

   1. CORE TOKENS: Raw, context-agnostic values (e.g., specific hex codes,
      pixel values). These should rarely be changed.

  2. SEMANTIC ALIASES: Context-aware variables that give meaning to the
    core tokens (e.g., --color-background-primary). This is the primary
    layer for theming.

   3. COMPONENT-SPECIFIC VARIABLES: Variables scoped to a specific component,
      often aliasing semantic variables for consistency.

   This structure makes it easy for a reviewer or future developer to
   understand and modify the theme.
