+ * These used to be environment variables, and flipping one meant editing the secrets file and
+ * restarting. Now they live in one database row ThreadCount's own administration can change, and
+ * the environment is an override rather than the source: SIGNUPS_DISABLED=1 or DEMO_DISABLED=1
+ * closes the door whatever the row says, so a box can still be locked down by hand — and nothing
+ * can reopen it until the variable goes, which is the point of an override.
+ *
+ * A missing row means open. A database error also means open here rather than closed: the only
+ * callers are the sign-up route, the sign-in page, the demo page and the demo entry, all of which
+ * fail on their own if the database is really down, and a transient error must not turn the
+ * public site into "sign-ups are closed" for the length of a blip. */
