/* SimpleGraph — base styles
   Data-ink ratio first. Minimal decoration. Let the data speak.

   Variables can be set on any ancestor element (container div, body, :root).
   Theme files set them on wrapper classes like .sg-midnight.
   Defaults are provided via var() fallbacks — no redefinition on .sg. */
