/**
 * Aggregates all four apps' appActive flags into one shared object, for
 * pages that need to know about apps OTHER than their own — the root
 * homepage's phase-cards and the shared nav fragment (edu_header.html),
 * both of which link to every app, not just one.
 *
 * Each app's own config.js (sibling config/ directory, config/README.md)
 * remains the single source of truth for its own appActive flag; this
 * just reads all four rather than introducing a second, separately-
 * maintained flag set that could drift from them.
