Two branches from parallel sessions, merged in that order because the first
removes shp-write and with it JSZip, which the second was working around.
Conflicts resolved by hand in vite.config.js: the JSZip chunk rule the second
branch added is dropped, since nothing reaches JSZip any more — shapefiles are
written by src/shapefile-write.js and shpjs 6 unzips with but-unzip. Vite's
preload-helper rule stays, which is what keeps the geotiff chunk out of the
startup preload. dist/ was rebuilt from scratch rather than merged, its hashed
file names being a conflict on every file.
Service Worker v26 now records both changes.
Verified on the merged tree: a production build preloads only the entry,
vite-helpers, bootstrap, openlayers and ol-ext — geotiff, shpjs and pako are
gone from startup, and Analyse still fetches its chunk and turf on first use.
Shapefile export, driven through the Export GIS modal, writes a zip holding the
point and polygon sets with their .prj and .cpg.
