ElyMail's window lists accounts and adds Gmail, Microsoft, iCloud
(app-specific password), IMAP and POP3 ones; a check logs in to both
servers and reports each. Accounts live in the store as JSON with a
case-insensitive unique address; secrets go to the keychain. Removal
names the cache it deletes, takes the secret first and puts it back
when local removal fails. Originals are set aside until commit and
restored after a crash. Requests are numbered so late results stay
with their own dialog. The account list is keyboard-navigable.
Passwords and refresh tokens go only to the system keychain; a refused
keychain keeps them in memory until exit and says why. Gmail and
Microsoft sign in by authorization code with S256 PKCE on a loopback
redirect; refresh tokens are kept, and revoked grants ask to sign in
again. Client IDs come from the build (env or oauth.env). ureq trace
records never reach the log.
