/api/favicon returned 404 in three paths (negative cache hit, non-200
upstream, sub-10-byte body), and since the avatar loads it as <img src>,
the browser logged a red 404 for every sender domain without a public
favicon - dozens per inbox view. Now it returns HTTP 200 with a 1x1
transparent PNG and an X-Bulwark-Favicon: missing header. Avatar.tsx detects
the sentinel via naturalWidth <= 1 in onLoad and falls back to initials, so
behaviour is visually identical without the console noise.
The plugin runtime received the active locale (init payload + 'locale-change')
and plugins could declare a `locales` map, but none of it was usable: the
locales never reached the runtime, and buildPluginApi exposed no i18n. So
plugin code calling pluginApi.i18n.t(...) (as the External Link Warning plugin
does) always got undefined and fell back to English.
Thread plugin locales end to end and surface an i18n API:
- ServerPlugin gains `locales`; the upload route persists manifest.locales
(alongside configSchema/settingsSchema), and /api/plugins surfaces it to the
client so it flows registry -> client -> sandbox host-bridge -> runtime.
- runtime sets __PLUGIN_LOCALE__ at init (not only on later 'locale-change')
and buildPluginApi exposes `i18n.locale` + `i18n.t(key, vars)` resolving
against the plugin's declared locales (manifest.locales) with English/key
fallback and {placeholder} interpolation.
Lets any sandboxed plugin localize its strings from its manifest.
Admins can upload custom mobile/desktop screenshots shown in the browser's
PWA install dialog, replacing the hardcoded Bulwark ones. Two new config keys
(pwaScreenshotMobileUrl/DesktopUrl), upload widgets in the admin Branding tab,
a sharp-based /api/pwa-screenshot/[variant] resize route, and manifest.ts picks
the custom screenshots when configured.
Like the other branding fields, screenshots are per-domain: they are
BRANDING_OVERRIDE_KEYS, the manifest and the /api/pwa-screenshot route resolve
them from the request host (domain override -> global -> Bulwark default), and
the admin Branding tab + upload/delete route handle them in a per-domain scope,
mirroring pwaIconUrl/faviconUrl.
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 signature separator is already controlled by the
signatureSeparatorEnabled setting (lib/email-composer), which prepends
'-- ' at compose time when enabled. Baking it into the fixture
double-prefixed it.
The multi-account refresh-token cookie slot wiring was half-implemented:
every account's refresh token ended up on slot 0, so "+ Add Account"
silently clobbered the previous account's `jmap_rt` cookie. On page
refresh, only the most-recently-added account had a working refresh
token; the others bounced to login.
Three coordinated changes:
1. `app/[locale]/login/page.tsx` (handleOAuthLogin): write the next-free
cookie slot to `sessionStorage['oauth_cookie_slot']` before redirecting
to the IdP. `loginWithOAuth` already reads this key but it was never
written, so it always defaulted to 0.
2. `stores/auth-store.ts` (loginWithOAuth): distinguish "no value set"
(`rawSlot === null`) from "value is 0". Previously
`parseInt(getItem(...) || '0')` collapsed both cases, making the
`getNextCookieSlot()` fallback unreachable.
3. `stores/auth-store.ts` (loginWithServerSso) +
`app/api/auth/sso/complete/route.ts`: pass the slot through the body of
the POST and use it for `refreshTokenCookieName(slot)`. Same pattern as
the existing `/api/auth/token POST` that already accepts a slot. The
server defaults to 0 for back-compat with any caller that omits it.
After the fix, signing in with multiple accounts produces distinct
`jmap_rt`, `jmap_rt_1`, `jmap_rt_2`, ... cookies (matching the cookieSlot
field in account-store) and all accounts survive a page refresh.
Repro before the fix:
- Sign in with one account, refresh — works.
- Click "+ Add Account", sign in with a second account, refresh — second
account vanishes from the dropdown; switching to the first account in
the dropdown still shows the second account's identity in the From box.
