Tiles get an absolute grid slot instead of a packed order: a tile lands exactly
where it is dropped, dropping on another tile swaps the two, everything else
stays put, and empty cells and empty pages persist. The mockup previews the
result while dragging, a new page waits below the last one, "Pagina toevoegen"
keeps an empty page, empty cells accept the next tile from the picker, and the
mouse no longer selects text while dragging.
Storage and protocol stay version 1: `tiles[].slot` (0-47) and `pages` (1-8)
are additive, the layout message carries `slots` and `pages`. Firmware 0.2.26
places tiles on those slots (`place()` next to `pack()`); older firmware packs
in order as before and the editor says so.

Any tile can now be double width: pack() in runtime_model.h places wide
tiles in the left column and the manager preview follows the same rules.
New cards: built-in clock (digital or analog, screen.clock), five-day
weather forecast on a wide weather card fed by weather.get_forecasts,
history sparkline for sensors, sunrise/sunset (sun.sun), live kitchen
timer (timer.*, tap starts or pauses) and presence (person.*). The
manager pre-computes time-zone and forecast extras in a new 'x' object
and refuses layouts with new domains until the screen runs 0.2.14.
The self-test follows the packing, checks custom card parts and wide
widths, and diagnostics/send_layout.py pushes a demo layout of every
card type for render checks without Home Assistant. App 0.2.12,
firmware 0.2.14.
