   landing.css — tools.kfagency.net

   Direction: technical instrument, editorial. The audience is media buyers and
   agency strategists; the product is deterministic calculators and document
   generators. So it reads like an instrument panel and a print masthead, not
   like a friendly SaaS page.

   Deliberate departures from the app shell:
   · Dark ink canvas. The gradient is a hairline accent and one hero moment,
     never a wash — a gradient over everything is the thing that makes a page
     look generated rather than designed.
   · The kfagency.net type stack: Space Grotesk for display, DM Sans for text,
     Cairo for Arabic. Figures use the display face with tabular numerals
     rather than a webfont monospace.
   · Tools are a numbered editorial index with rules, not a grid of emoji cards.

   Self-contained: this file owns its own tokens so the app shell can stay
   light without either fighting the other.
