+// Pushmeldingen in beheer (pages/admin-push.ejs) -- verplaatst uit inline script, shaer-bqr.
+//
+// Inline script in een pagina wordt door de CSP geweigerd zodra je die pagina via
+// een link BINNEN de site opent: de nonce rouleert per verzoek (shaer-0i6). Dit
+// bestand wordt door de bootstrap in shell.ejs geladen en heeft dat probleem niet.

+// Alles hier hoort GEDELEGEERD te luisteren (op document, niet op een element dat
+// er nu staat) en tegen een tweede aanroep te kunnen.
