// ============================================================
// ADMIN — SEARCH SOURCES
// ============================================================
// The screen that decides whether a generated resource may search the web or
// PubMed, and holds the keys for both.
//
// This exists because that card could not previously be tested at all: there
// was no admin account to log in as, so it was checked by reading its markup
// and confirming the element ids matched the handlers. That verifies the wiring
// and nothing about whether an administrator can actually reach the screen,
// whether an ordinary user is kept off it, or whether a saved key survives a
// round trip.
//
// Two things are asserted that are easy to get wrong and expensive to get
// wrong: the routes are admin-only, and a key is never sent back to the browser
// in readable form.
