/*
 * miplann landing page.
 *
 * The same ground as the app, not a brochure about it. Clicking through should
 * feel like walking further into the same place — same near-black, same ice
 * blue, same type. A bright marketing page that opens into a dark app always
 * reads as two products.
 *
 * Apple's page grammar — huge tight headlines, short centred lines, generous
 * space, filled/outlined pill buttons — but their pages are mostly photography,
 * and we have none. So the product shot is the product: a live, running copy of
 * the app in the hero, and the two features that make it different are things
 * you press rather than things you read about.
