Upstream 1.7.2 prefixes most hand-written URLs with basePath via apiFetch /
withBasePath, but four subpath-relevant spots were missed:
- host-bridge: the sandbox iframe src was a bare "/plugin-sandbox" -> 404
under NEXT_PUBLIC_BASE_PATH, breaking all plugins. Wrap in withBasePath.
- host-api doHttpPost: the same-origin /api/* plugin proxy used raw fetch on
url.pathname -> 404 under a subpath. Route it through apiFetch.
- admin branding preview <img>: unprefixed src -> broken thumbnail.
- (sandbox) layout: drop the Geist font + globals.css imports. The sandbox
runs with an opaque origin, so those assets are CORS-blocked; the plugin
bundle and all host API calls travel over the postMessage bridge, so no
same-origin asset fetch happens there.
The quick-reply box built its body with appendPlainTextSignature, which runs
the identity's HTML signature through htmlToPlainText, and sent a text-only
message (htmlBody was undefined). A formatted signature (e.g. <strong>…) was
therefore flattened to plain text in the sent mail, even though it previewed
correctly in the identity editor. The full composer already builds an HTML
signature block; quick reply did not.
Add an appendHtmlSignature helper (mirrors the composer's send-time block) and,
when the sending identity has an HTML signature, send a matching HTML body from
handleQuickReply so the markup is preserved. Text-only identities keep the
plain-text-only behavior.

The dev mock's Identity/set discarded its payload and Identity/get always
returned a static list, so saved identities never round-tripped in local
development. Persist create (with mayDelete: true), update, and destroy in
place, mirroring handleMailboxSet, so signature edits stick when testing
without a real JMAP server.

The <=640px rule zeroes .email-content-text horizontal padding, so
plain-text (prose) emails render flush against the viewport edge on
phones, which hurts readability. Use a reduced 0.75rem gutter instead
of 0 — still maximizes width for wide content but keeps text off the
screen edge.
