/* This is a single dark "magical" brand look by design — intentionally kept
   distinct from the warm/light editorial look of client sites like
   tapasyaConstructions, so KLMN2's own site doesn't read as one of its own
   templates. No light-mode override, same reasoning as that sibling project:
   the brand should look the same for every visitor. */
