T6003: Unknown layout

Cause

A page's <page> block names a layout that does not exist in app/layouts/.

Example

<page>
{ "layout": "defualt" }
</page>
<template><main><h1>Hi</h1></main></template>

What you see

ERROR  T6003  app/pages/about.tess:2:13
  Unknown layout "defualt".
  Did you mean "default"?
  Run `tessera explain T6003` for details.

Fix

Use the name of a file in app/layouts (the hint suggests the nearest), false for none, or create the layout.
