 **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.

 If you enable Basic Auth, protect the app with HTTPS. HTTP Basic credentials are not safe on plain HTTP. Also note that the app's permissive CORS policy is a deliberate trusted-network tradeoff, so cross-origin browser JavaScript is not a reliable way to use that Basic Auth gate.

 `__CLOWNTOWN_DO_CLOCK_WRAPAROUND=true` is a last-resort clock remediation for nodes whose RTC is stuck in the future and where rescue-mode time setting or GPS-based time is not available. It intentionally relies on the clock rolling past the 32-bit epoch boundary, which is board-specific behavior and may not be safe or effective on all MeshCore targets. Treat it as highly experimental.
 
+## Sub-Path Reverse Proxy
+
+RemoteTerm works behind a reverse proxy that serves it under a sub-path (e.g. `/meshcore/` or Home Assistant ingress). All frontend asset and API paths are relative, so they resolve correctly under any prefix.
+
+**Requirements:**
+
+- The proxy must ensure the sub-path URL has a **trailing slash**. If a user visits `/meshcore` (no slash), relative paths break. Most proxies handle this automatically; for Nginx, a `location /meshcore/ { ... }` block (note the trailing slash) does the right thing.
+- For correct PWA install behavior, the proxy should forward `X-Forwarded-Prefix` (set to the sub-path, e.g. `/meshcore`) so the web manifest generates correct `start_url` and `scope` values. `X-Forwarded-Proto` and `X-Forwarded-Host` are also respected for origin resolution.

 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`.
+
 ## Security Posture (intentional)
 
 - No authentication UI.
