 * nav: existing app topbar (harmonized on landing) / N1a on doc pages · footer: Ft8 marquee (landing) / Ft2 inline (docs)
 * H2 diptych knobs: ratio=7/5, right=interactive proof, divider=negative space
 * audience: casual players · use: start playing in seconds · tone: playful
 * Scoped: .landing-page (in-app view) and body.doc-page (terms/legal). Game views untouched.
