  Build the complete SCSS variables dict passed to toCSS as hugo:vars.
  Two categories:
    - Internal: theme config (base URL, logo, loading image) — highest priority
    - Appearance: defaults + derived + user config ([params.appearance])
  Reference: assets/scss/_variables.scss
  Note: Color values must use hex format (e.g. "#ff0000"), CSS named colors (e.g. "red") are not supported
  because Hugo's isTypedCSSValue only recognizes hex colors, CSS functions, and CSS units.
