/* Spendy landing — dark gradient fintech.
 *
 * Direction chosen by the user from three (see public/_design/directions.html). The reference
 * class is Stripe / Mercury / Robinhood: a deep ground, ONE feathered gradient mesh, hairline
 * detail, and real product data as the graphic. Our own brand green stays the accent rather
 * than drifting to the generic fintech navy — the app is green and the store art is green.
 *
 * Type is Sora (display) + Plus Jakarta Sans (body). Deliberate: a system stack carries no
 * identity, and it was part of why the first two attempts read as pale.
 *
 * The page is dark at every system setting. That is a brand decision, not an oversight: a
 * light variant of this direction would be a different design, not a theme of it.
