 It downloads `https://awpycs.com/<build>/tris.zip` and writes the requested maps
 to `.cache/meshes/`. Add `--publish` to push + tag them to the CDN (see Hosting).
 Bump `AWPY_BUILD_ID` when awpy ships data for a newer CS2 patch.
 
-**Auto-decimation:** maps over `MESH_MAX_MB` (default 30) are *not* dropped — the
-script snaps their vertices to a grid and dedups degenerate/duplicate triangles
-until they fit, so big active-duty maps still come through (e.g. inferno
-97→~19 MB, train 55→~14 MB, ancient 35→~12 MB). This is the same idea as the
-"weld + simplify" step below, just built in and pure-JS.
