   Nabaflow — nabaflow.com
   Stylesheet built on the "cisco" design system (designmd):
   dark-mode-first, absolute high-contrast binary (near-black / pure white),
   4px spacing base, sharp 4px cards + pill CTAs, Inter at unified medium
   weights, conservative 250/333/800ms motion on cubic-bezier(.4,0,.2,1).
   Retinted to the Nabaflow palette: deep water blue, cool concrete grey,
   amber reserved strictly for alert states.
