This repository has no deploy script or CI: package.json only builds to
dist/ (gitignored), yet dist2/ is committed and is what actually gets
served. The procedure was folklore reconstructed from commit history each
time someone deployed.
Write it down, including the two traps found while deploying fb8f7ca:
- vite's emptyOutDir defaults to true when outDir sits inside the project
root, so a bare `vite build --outDir dist2` deletes the hand-placed test
assets in dist2/samples (configBak/, dwg_18.3mb.dwg). Always pass
--emptyOutDir false.
- npx vite can fail here with `Missing script: "vite"`; call
./node_modules/.bin/vite directly.
Also notes the open issues: no build:dist2 script, old hashed bundles
accumulating in dist2/assets, and test fixtures living inside the build
output directory.

Mirrors hmwebviewer's rust/dwg-wasm change into the sample: the wasm
artifact plus the parser wrapper, which now goes through parse_dwg_json
and JSON.parse instead of the JsValue-returning parse_dwg.
Building the whole result as a serde_json::Value tree pushed the live
wasm heap near 2.9GB for a 19MB drawing, and the allocator's cost grows
with that heap, so parsing went quadratic — 354s, with the tab frozen
throughout. Streaming one entity at a time keeps it linear: 2.5s.
The same build also fixes three bugs that drew stray 4km grey shapes
where two CF-PATT SOLID hatches should be. Max hatch span 4655 -> 110.
Adds two docs recording both investigations, in the format of the
existing ones: measurements, the hypotheses that were ruled out, the
fixes, regression checks, and the MPL-2.0 position (acadrust is
unmodified, so no new source-disclosure obligation arises).
