/* Lumelo marketing site.
   Layout concept: left-aligned editorial grid on cool paper. The dark "why trace" card is the single bold
   element; everything around it stays quiet. One cobalt band carries the offer. Record IDs, run logs and
   report figures use a mono face because that is what the product's own timeline looks like. */
