Explain isolated network behavior on the app network card

Add an info alert to the isolated network access section covering what users should know about the implementation: the app appears as a separate device, IPv6 is automatic via SLAAC, the host and the app cannot reach each other on the isolated network by design (Supervisor communication like ingress is unaffected), and apps that introspect host interfaces may behave differently.

 - **Test accessibility**: Ensure components are accessible
- **Optimizing chart data processing**: When optimizing chart data transforms (history, statistics, energy, downsampling), follow the playbook in [`test/benchmarks/README.md`](test/benchmarks/README.md) — it has seeded fixtures, characterization (snapshot) tests that pin current output, and `vitest bench` benchmarks (`yarn test:bench`) for before/after comparison. Optimizations must keep output bit-identical.

-A section can group its pages under named subsections instead of one flat list. Use this for large categories where related pages should sit together.

- `subsections` is an array of `{ header, pages }`. It is mutually exclusive with a flat `pages` array on the same group.

- Listed pages keep their per-subsection order.
- Any pages found in the category but not listed in a subsection are collected into a generated `Other` subsection, appended alphabetically. The `Other` subsection is omitted when there are no leftovers.
- A listed page that does not exist still logs an error during `gather-gallery-pages`.

 # Welcome to Home Assistant Design

-This is the design gallery for the Home Assistant frontend: a living reference of working components, dashboard cards, and brand and copy guidance. Every page runs outside a Home Assistant instance, so you can explore the interface, try components in isolation, and review changes against a consistent baseline.
+This portal aims to aid designers and developers on improving the Home Assistant interface. It consists of working code, resources and guidelines.

-## Browse the gallery
+## Home Assistant interface

- [Brand](#brand/logo): the logo, personality, and the story behind the Open Home.
- [Components](#components/ha-button): the `ha-*` component library with live demos and API notes.
- [Dashboards](#lovelace/introduction): Lovelace cards rendered from real card configuration.
- [More Info dialogs](#more-info/light): the more-info experience for each entity type.
- [Automation](#automation/editor-trigger): trigger, condition, and action editors, plus trace views.
- [Users](#user-test/user-types): the audiences we design for.
- [Date and time](#date-time/date): date and time formatting examples.
- [Miscellaneous](#misc/entity-state): smaller utilities and patterns, plus how to edit this gallery.
+The Home Assistant frontend allows users to browse and control the state of their home, manage their automations and configure integrations. The frontend is designed as a mobile-first experience. It is a progressive web application and offers an app-like experience to our users. The Home Assistant frontend needs to be fast. But it also needs to work on a wide range of old devices.

-## Testing and playground
+### Material Design

-Every page runs against fake state, so you can interact with components safely and reproducibly. Treat the demo pages as a playground: change a value, resize the window, or switch the layout to right-to-left to check spacing and direction. Use the gallery to reproduce a UI state in isolation before debugging it in a full Home Assistant setup.
-
-Open **Settings** from the gear icon in the sidebar to switch between light and dark themes or preview the interface in right-to-left.
+The Home Assistant interface is based on Material Design. It's a design system created by Google to quickly build high-quality digital experiences. Components and guidelines that are custom made for Home Assistant are documented on this portal. For all other components check <a href="https://material.io" rel="noopener noreferrer" target="_blank">material.io</a>.

Stefan Agner	78d4072049	Explain isolated network behavior on the app network card Add an info alert to the isolated network access section covering what users should know about the implementation: the app appears as a separate device, IPv6 is automatic via SLAAC, the host and the app cannot reach each other on the isolated network by design (Supervisor communication like ingress is unaffected), and apps that introspect host interfaces may behave differently.

Stefan Agner	f2827d0ab6	Show the endpoint MAC address on the app network card Display the saved endpoint MAC below the IP address field of the isolated network access section, so users can set up router or firewall rules right where they configure the endpoint.

Stefan Agner	22b83b20fc	Show the MAC address of isolated app network endpoints The Supervisor now reports network_isolation_mac, a stable MAC derived from the static IP that is known as soon as isolation is configured. Show it next to the IP on the app info tab, including while the app is stopped, so users can create router or firewall rules before the first start.

Stefan Agner	65f7d65462	Add isolated network access settings for apps Apps that use host networking can now be switched to an isolated network endpoint (macvlan) from the network card on the Configuration tab, when the Supervisor reports network_isolation_available. The card gains a toggle, an interface select populated from the network_isolation_capable host interfaces, and an IPv4 address field. Saving posts the network_isolation option and suggests an app restart, same as port changes. The info tab shows the assigned IP while the app is running.
