/* Runo — landing and pricing.
 *
 * These are the only pages a stranger sees before deciding anything, so they
 * get room to breathe: wider measure, larger type, more vertical space than
 * the app.
 *
 * The hero backdrop is CSS and SVG rather than a photograph. Not a
 * compromise — it is the better answer here: no third-party request (a CDN
 * is forbidden by the privacy posture and a self-hosted photo is megabytes
 * on a phone), it fits any viewport without art direction, it follows the
 * theme, and it can stop moving when asked. To swap in a real image later,
 * override `background` on `.hero-scene` and delete the three glows.
