// The legacy SPA served the same single page for every top-level path and just
// scrolled to the matching section. We preserve those URLs (they are canonical
// in sitemap.xml) by rendering the same page for each known route and 404ing
// anything else.
// /about, /docs, /pricing, /privacy, and /terms are now real routes
// (app/about, app/docs, app/pricing, app/privacy, app/terms); the rest still
// render the homepage SPA scrolled to their section. Every key left here MUST
// have a matching section id in `renderPageMarkup` -- /privacy used to be
// listed without one, so it served the whole homepage and scrolled to a card
// that only described the page that did not exist.
