1.12 addresses a map by a (continent, zone) pair of dropdown indices — a
position in two lists, which moves when a zone is inserted — and publishes no
map's rectangle on any other map at all, because its window draws one zone at a
time into a fixed 1002x668 frame and never needs to know where that zone sits.
A seamless, pannable map is exactly that missing relation.
`script/uimap.rs` builds the tree as a pure function of the catalog
`ui_world_map.rs` already pushes, rebuilt inside both setters so the graph and
the catalog cannot disagree. No new DBC read, so nothing here can contradict
what the stock map window itself draws.
It is built from OctoWoW's own rows, which is the point: 175 against stock
1.12's 51, with 124 maps added and 49 shipped rects re-tuned. Era's uiMapIDs
are reused where the map is the same map, joined on the WorldMapArea art folder
rather than the zone name, because the folder is the column a realm has no
reason to touch — this realm spells Azshara's `Aszhara` and Hillsbrad's
`Hilsbrad` exactly as 1.12 does. A row Era has no counterpart for is minted
from its own AreaTable id.
One realm quirk is handled with its measurement: a third `areaID == 0` row
whose art folder is `World` is the sheet's own row, which the reference's
catalog walk files beside the two continents — `SetMapZoom(3, 0)` then
`GetMapInfo()` answers `World`. Left in, it is a phantom continent carrying a
second copy of all 39 Eastern Kingdoms zones.
Art is answered as paths, so the chain serves the upscaled pack; the layer
geometry is the logical 1002x668 / 256x256, because normalized fractions are
invariant under a uniform upscale.
The harness now seats the player a world position and the per-frame map feed,
because every verb that answers *where* the player is reads the position, not
the zone name. Corpus: 85 ok / 1 fail, roster and digest unchanged.
