`mobile-header`

A mobile stack header with back, title and actions. Host chrome; agents never emit it.

**Logical CSS, so right-to-left mirrors correctly.** Layouts compose with logical CSS properties (inline-size, inset-inline-start), so right-to-left locales mirror without component changes, and full-page layouts render real landmarks (main, banner, contentinfo).

## For agents

The live preview, prop editor and copyable code run in the browser. The component manifest holds the same props, events, examples and guidance as data. The live parts run in the browser and are not in this Markdown; the operations below do the same work through the read-only MCP server at https://texuli.com/mcp (no sign-in; see https://texuli.com/auth.md).

MCP operations ([reference](https://github.com/DailybotHQ/texuli/blob/main/packages/tools/docs/ops.md#operations)):

- `component.get`: Read a component manifest with `{"id":"mobile-header"}`.
