// /api/email/* — auth, then forward to officer-email. No routes of its own and no mail knowledge: not a
// message, not a folder, not an IMAP or SMTP credential.
//
// The mail store, the HTTP routes, account CRUD, resync and IMAP validation all used to live in the
// platform — ~1,800 lines against a 314-line sidecar, with the sidecar importing BACK into the platform to
// reach them. They were moved into the sidecar before this extraction, which is the only reason this file
// is twenty lines and the extraction was tractable at all.
//
// ── The prefix is DERIVED, not written ──
//
// `createSidecarProxy` strips `prefix.length` characters to build the sidecar path, so a literal
// '/api/email' is correct only for a first-party publisher. Published by anyone else this mounts at
// `/api/p/<publisher>/email`, and a literal would forward `/alice/email/messages` to a sidecar expecting
// `/messages`. `mountPrefix` is the one function allowed to know about provenance.
//
// A from-scratch mailbox sync holds a proxied request open well past the 60s idle default, hence the
// timeout; it applies to the whole prefix because the proxy must not know which routes are slow.
