Sizes single, wide and full in web/src/model/layout.ts (a full tile covers the six cells of a page and starts
it; packing, fitting, arranging and page counting know it), the full card on the mockup, Size with Full page
and its firmware hint in the tile drawer, controls defaulting to none on a full tile, navigation tiles
(screen.page_1..8: Goes to page, size normal or double, icon and colour only, "Page n ›" on the card), the
tile limit of 48 from firmware 0.2.62, the "Screen" domain label. Vitest and the Python source tests cover it.
The add-on side of this round lives on the peer branch fullpage (4be6153).
