-## Server Roaming (UserSave tier)
-
-`EnableServerLayouts` (default `true`) roams the **UserSave** tier through the grid's own `SignalRClient`,
-using the framework tags defined in `AcSignalRTags` (AyCode.Services):
-
-| Tag | Value | Params (in order) | Returns |
-|---|---|---|---|
-| `GetGridLayoutTag` | 90010 | `key` (string), `userId` (int) | layout JSON, or null |
-| `SaveGridLayoutTag` | 90011 | `key`, `layoutJson`, `userId` | bool |
-| `DeleteGridLayoutTag` | 90012 | `key`, `userId` | bool |
-
-- The `key` is the full composite UserSave storage key (it already contains the user id); the server treats
-  it as an opaque string. `userId` comes from `GetLayoutUserId()`.
-- **Server communication happens exclusively on user clicks** (Save/Load layout toolbar buttons) — never on
-  grid init, toolbar init, detail-row expand, or prerender.
-- All server calls are **best-effort** (`try/catch`): offline, or when the server does not implement the
-  tags, behavior degrades to the local-only flow without errors.
-- The server must implement the three tags; the storage schema is the consumer's choice.
-- The `AutoSave` and `Splitter` tiers never touch the server.

->
-> **Strict rule**: AyCode.Blazor code, types, namespaces, topic IDs, and any other `.md` files MUST NOT name any specific consumer listed here. **This is the SINGLE place** in ACBLAZOR that may name consumer repos.

-
-- A breaking change to `MgGridBase` / `MgGridWithInfoPanel` affects both consumers above.

-- DevExpress version bumps cascade to every consumer (license + API compatibility check per consumer).
