Meld v1.2.0

Offline, faster, cleaner.

1.1.0 made builds bigger; 1.2.0 makes them offline and fast. You can now bake a whole region's OSM
once from a local Geofabrik .pbf and generate with zero Overpass calls, and the OSM cache is keyed
to a fixed map grid so two overlapping selections reuse the same tiles instead of re-downloading. On
the generation side, the biggest per-cell cost turned out to be a supplementary building fetch that
ran on every cell even when you'd turned buildings off, that's gone for roads-only builds (a measured
cell dropped from ~29s to ~4s), and each cell now reads its OSM straight from the shared tile cache
with no merge step at all. Your drawn area is finally remembered across a restart, per world. And the diagonal
water-and-sand "wedges" that sometimes slashed across otherwise-perfect terrain are fixed.

Highlights:

• Build offline. Drop Geofabrik .osm.pbf files in a folder, bake them once, and generate with
  no Overpass, pair it with the elevation packs from 1.1.0 for a fully local region. New OSM data
  pack card: check coverage, bake, scan folder, watch progress.
• OSM cache that reuses. Map data is cached on a fixed grid, so a 90%-overlapping selection
  downloads only the new edge, and an identical re-run downloads nothing.
• Much faster cells. The Overture building fetch (about 93% of a cell's time) is skipped on
  roads-only builds; with buildings on it now caches to disk and downloads once instead of per cell.
  Each cell reads its OSM tiles directly with no merge step, the terrain warm is skipped when elevation
  is already cached, and rate-limited tiles retry-and-cache instead of re-fetching every run.
• Your area is remembered. The selection and cells save into each project and redraw on restart,
  so there is no re-drawing the country after a server restart.
• No more water wedges. Triangular water/sand bleed across terrain (from water polygons that
  cross a cell edge) is fixed by clipping every water ring to the cell before it's filled.
• Detail + reliability. Road-detail clean/compact modes, a custom Overpass URL, sub-world
  operations, and disk-recovery of orphaned patches.

Setup: pip install osmium for .pbf baking. A region is fully offline once it's both elevation-
and OSM-packed. Restart the server after a bake. Buildings are off by default; turning them on
downloads Overture once per partition (slow the first time, cached after).

Get it: clone Teddy563/meld, pip install -r requirements.txt,
python server.py, and open http://127.0.0.1:5630. The generator is the custom
Arnis fork, shipped as arnis.exe.
