Every Kiduna URL that can be shared gets a 1200×630 card. Two families: a property card for the ecosystem and its surfaces, and a work card for a specific artifact — a nightpaper, a movement, a realm. Both keep the same anatomy: espresso ground, celestial artwork held to the right, all type in the left half, gold as the single accent.


KIDUNA
A New Architecture for Agentic Civilization
Scale compounds agency.
1200×630 (1.91:1). Export at 2× for retina. Under 1 MB — PNG for type-led cards, JPEG q85 when artwork dominates.
72px margin all sides. Type stays in the left half; artwork never crosses the centerline. Nothing critical in the outer 5% — feeds crop it.
Headline Goudy Heavyface, 54–70px, upright. Sub in Avenir 28–32px. Wordmark either the linear lockup or Avenir Heavy at .42em tracking. Never below 28px.
Espresso #1C140D ground, cream white #FFFFE6 headline, sun-gold for the emphasis line, skyblue reserved for one closing thought. One accent per card.

Artwork above is placeholder celestial imagery, held to the right and faded into the ground so the left half stays legible at feed size. Replace with final art at 2×; keep the fade.
