Read the grid layout of an xTiles page (view) by viewId: every tile with its title and grid position (x, y, w, h), plus the grid bounds (max width/height) and minimum tile size. Coordinates use the xTiles grid — (x, y) is the tile’s top-left corner and (w, h) is its size, in grid cells. Use this to inspect tile placement and valid bounds before repositioning with xtiles_set_page_layout. Which colours, styles, sizes and positions to use: xtiles://guide/markdown/design.
