-**Note:** Runtime app settings are stored in the database (`app_settings` table), not environment variables.

They are configured via `GET/PATCH /api/settings`. The backend still carries `sidebar_sort_order` for compatibility and migration, but the current frontend sidebar stores sort order per section (`Channels`, `Contacts`, `Repeaters`) in localStorage rather than treating it as one shared server-backed preference. MQTT, bot, webhook, Apprise, and SQS configs are stored in the `fanout_configs` table, managed via `/api/fanout`. If the radio's channel slots appear unstable or another client is mutating them underneath this app, operators can force the old always-reconfigure send path with `MESHCORE_FORCE_CHANNEL_SLOT_RECONFIGURE=true`.

 **Warning:** This app is for trusted environments only. _Do not put this on an untrusted network, or open it to the public._ You can optionally set `MESHCORE_BASIC_AUTH_USERNAME` and `MESHCORE_BASIC_AUTH_PASSWORD` for app-wide HTTP Basic auth, but that is only a coarse gate and must be paired with HTTPS. The bots can execute arbitrary Python code which means anyone who gets access to the app can, too. To completely disable the bot system, start the server with `MESHCORE_DISABLE_BOTS=true` — this prevents all bot execution and blocks bot configuration changes via the API. If you need stronger access control, consider using a reverse proxy like Nginx, or extending FastAPI; full access control and user management are outside the scope of this app.

+> [!WARNING]
+> RemoteTerm does *full* management of the radio, meaning that once a radio is connected to RemoteTerm, all contacts/channels will be imported and offloaded to RemoteTerm and the contacts actually synced to the device will be governed by RemoteTerm. This means that RemoteTerm can be a poor fit for users who are looking to swap radios in and out, maintaining radio state (favorites, channels, etc.) irrespective of app usage.

 UI styling is mostly utility-class driven (Tailwind-style classes in JSX) plus shared globals in `index.css` and `styles.css`.
 Do not rely on old class-only layout assumptions.
 
+### Canonical style reference
+
+`SettingsLocalSection.tsx` contains a **ThemePreview** component with a collapsible "Canonical style reference" section. This is the authoritative catalog of text sizes, button variants, badge patterns, and interactive elements used throughout the app. **When adding or modifying UI, match the patterns shown there rather than inventing new ones.**
+
+Key conventions documented in the reference:
+
+- **Text sizes** use `rem`-based Tailwind values so they scale with the user's font-size slider. Do not use hard-locked `px` values (e.g., `text-[10px]`). The canonical sizes are `text-[0.625rem]` (10px), `text-[0.6875rem]` (11px), `text-[0.8125rem]` (13px), plus standard Tailwind `text-xs`/`text-sm`/`text-base`/`text-lg`/`text-xl`.
+- **Section labels** use `text-[0.625rem] uppercase tracking-wider text-muted-foreground font-medium`.
+- **Buttons** use the shadcn `<Button>` component. Semantic color overrides (danger, warning, success) use `variant="outline"` with `className="border-{color}/50 text-{color} hover:bg-{color}/10"`.
+- **Badges/tags** use `text-[0.625rem] uppercase tracking-wider px-1.5 py-0.5 rounded` with `bg-muted` (neutral) or `bg-primary/10` (active).
+- **Clickable text** (copy-to-clipboard, navigational links) uses `role="button" tabIndex={0}` with `cursor-pointer hover:text-primary transition-colors`.
