Every plugin iframe loaded /plugin-sandbox, a force-dynamic Next page.
Each frame then fetched, parsed and hydrated Next's client router on top
of React and the runtime, and the server rendered the page once per
frame, one after another when a dozen plugins started together.
Sandboxed frames have opaque origins, so the browser's code cache never
helps, and they run on the host page's main thread: with 12 plugins
the frames took 2.5-3 s to come up after the app had loaded.
The sandbox routes now return a small HTML page with the UI kit's
stylesheet and the runtime as an ES module, both built ahead of time:
- `scripts/build-plugin-sandbox.mjs` bundles the runtime with esbuild
and compiles `plugin-kit.css` with the app's Tailwind setup into
`public/plugin-sandbox-assets/`, with a manifest. Named Tabler imports
are pointed at the icons' own files, so the full icon set stays in a
chunk that only loads for an icon name the kit doesn't ship.
- `npm run build`, `npm run dev`, the Dockerfile and the perf-guard
workflow run it before `next build`.
- `lib/plugin-sandbox/sandbox-document.ts` writes the page; proxy.ts
still sets the sandbox CSP and the script carries its nonce.
- The assets are served from public/ with CORS and immutable caching.
A frame on an idle page is ready in 255 ms instead of 362 ms, eleven at
once in 1.0 s instead of 2.1 s.
Plugins running in iframe sandboxes previously lacked access to the user's regional formatting settings (dateLocale, timeFormat 12h/24h, timeZone, and firstDayOfWeek) unless they requested privileged settings:read permissions.
This mirrors the host's resolved presentation preferences into the plugin sandbox:
- Adds RegionalSnapshot (locale, dateLocale, hour12, timeZone, firstDayOfWeek) to BackgroundInit, SlotInit, and LocaleChangeMsg.
- Implements snapshotRegionalSettings() in host-bridge, reusing host resolveDateLocale() and getEffectiveTimeZone().
- Subscribes stores/plugin-store.ts to useSettingsStore to broadcast updates to running sandboxes when regional preferences change.
- Exposes api.i18n.formatTime(date, options) and api.i18n.formatDate(date, options) along with regional getters on api.i18n.
A new feature gate, tagsAboveSharedEnabled (default off, so the sidebar
keeps its order), lists the Tags section above the shared mailboxes
instead of below them. With many shared mailboxes expanded, the tags
otherwise end up out of sight. In Mountain View the tags then follow the
Labels list directly, also when More is open.

keywords.add now records the plugin on each definition it adds
(addedBy). keywords.update changes the label, colour or visibility of
those definitions, never their id; keywords.remove deletes them, as
Settings > Tags does, and leaves the keywords on messages alone. Both
need settings:write and skip every other definition, so a plugin cannot
rename or delete the user's own tags or another plugin's.

Some user-facing strings still said "Bulwark" on a deployment with its own
APP_NAME: Settings > General > Default apps (protocol handlers), the "Open
Bulwark" notification, the rate-limit banner and toast, the plugin connect
dialog, one plugin permission text and the connector page.
These strings now take an {appName} placeholder, filled by productName():
the configured APP_NAME, or "Bulwark" when it is unset or the default
"Webmail" (the same rule as the TOTP issuer and the About card, #1160).
A stock install reads as before.
The settings search (the settings page and api.app.searchSettings) indexes
these texts with the name filled in, so "bulwark" or the configured name
finds Default apps and no result carries the raw placeholder.
Locales: the 13 keys in every locale that has "Bulwark" in them. Languages
that inflect the name (cs, et, hu, ko, ro, sk, tr) use a neutral form such
as "{appName} uygulamasında" instead of a declined "Bulwark'ta"; a native
check of those is welcome.
Not changed on purpose: the mobile app, push relay, Lite, demo and admin
texts, which speak about Bulwark itself.
