 This guide is for anyone, person or AI coding tool, building a Termix plugin. It ships inside
 `@termix-ssh/plugin-sdk`, so the copy in your `node_modules` always matches the SDK you have installed.

   `PanePrompt` for small prompts.
 - Every tab or panel sits in `PanelShell`. Lists use `PanelList` and `ListRow`, add with `AddButton`,
   forms end with `FormFooter`, empty lists show `EmptyState`.
+- Tile pages use `TileGrid` with `TileFrame` around each tile and `TilePicker` beside it while editing. Slots are
+  `{ id, x, y, w, h }` on 12 columns (`h` null for the natural height); save them where your plugin keeps
+  preferences and run saved ones through `sanitizeTiles`. Add with `appendTile`. Needs Termix 26.11.1.
+- A dashboard card with `entries` can be placed many times: each entry has a title, a group and a `config` the
+  card gets back as `config` (save changes with `setConfig`, keep it small). Operations Center uses this for
+  status and action tiles.
 - Card grids use `DataView` with `ViewToggle`. Pass `columns` and `onColumns` to `ViewToggle` and the same
   value as `size` to `DataView`, so users can pick Auto (as many as fit) or a fixed number of cards per
   row. `usePluginPanelView` keeps the choice as `columns`. Older Termix versions ignore both props.
