A "⤓ Download (zip)" button in the browse toolbar (shown once a
directory is loaded) downloads the directory you're currently
viewing — and everything under it you're allowed to see — as a single
.zip. Navigate into a subfolder first to grab just that subtree.
- Server mode: an <a download> at "<currentPath>?zip=1" — zddc-server
streams the ACL-filtered zip (see the previous commit), nothing held
in the browser.
- Offline (file://) mode: new browse/js/download.js walks the picked
folder with the FS-Access API in two passes — metadata first (so it
can confirm() before loading >~2000 files / ~500 MB into memory),
then bytes — bundles with the already-vendored JSZip, and triggers a
blob download. Hidden entries (".":/"_"-prefixed) are skipped, the
zip's top level is "<folderName>/…" so it unpacks tidily, and the
status bar shows progress.
Wired in browse/js/events.js (button click + show/hide alongside the
refresh button); concatenated into browse/build.sh; ARCHITECTURE.md +
AGENTS.md note the ?zip=1 endpoint and the button.
