• CSS custom properties for theming: inheritance, fallbacks and @property

  Custom properties (--name) cascade and inherit like other properties and are read with var(--name, fallback); an invalid substitution does not discard the rule but falls back to the initial or inherited value, and @property adds a type, an initial value and animation support. Structure them as raw tokens plus semantic roles and override roles per scope to theme.
