/**
 * Single source of truth for the 3 presentation modes/sales apps. `key`
 * doubles as the valid `defaultMode` config value (config-schema.js) and as
 * the route path segment (see Routes.jsx, AppSelection.jsx). `contentFile`
 * is the JSON this mode's route loads via ContentProvider
 * (services/content.jsx); `null` means the page doesn't fetch any content
 * (yet). A mode can use `contentFiles` (array) instead of `contentFile`
 * (single string) when its content is split across several smaller files -
 * ContentProvider fetches all of them and merges the results into one
 * `content` object, so consumers still read e.g.
 * `content.valuePartnership.points` regardless of which file it came from.
 *
 * `orientation` is each app's fixed, content-driven physical orientation
 * (confirmed with the content team, not device-dependent - Rad Enablement is
 * portrait-only, everything else landscape) - consumed by Stage.jsx to pick
 * a landscape vs. portrait reference resolution for the whole-app scale
 * wrapper. `resolveModeForPath()` below is the one place that maps a route
 * to its mode - reused by Stage and GeneralPageTracking so they can never
 * disagree about which mode a given path belongs to.
