Bundles Phase 2 polish + the user-requested header/breadcrumb work:
- Breadcrumbs replacing the plain currentPath span. Server mode
renders linkified ancestor segments (each <a> navigates to that
directory; the browser fetches browse.html, the new instance
auto-loads the listing). FS-API mode renders the rootHandle name
as a non-link (no ancestor handles to navigate). Both prefix the
path with a 🏠 root icon. Trailing slash + bold-current segment
match common file-explorer conventions.
- Subdued 'Select Directory' button in server mode. Once browse is
serving a real directory listing, the local-folder switcher is
available but visually quiet (btn--subtle: transparent, muted
color). FS-API mode keeps the primary styling (it's how the user
got there). New btn--subtle CSS class added to browse's tree.css.
A refresh button (⟳) appears next to it in both modes; clicking
it re-fetches the current root listing.
- Header consistency: browse now matches archive's header layout
(refresh + help buttons in addition to theme on the right). Help
is a placeholder for future help dialog wiring.
- File preview popup. Click a file row → opens a popup window with
the file rendered. Plain types (PDF, HTML, image) load in
iframes; TIFF + ZIP listings via shared/preview-lib.js's
renderTiff / renderZipListing helpers; text via <pre>; unknown
types → 'click Download' placeholder. Modifier-click (ctrl/cmd/
shift) and middle-click still open the file in a new tab via the
underlying <a target=_blank>. Single popup window is reused
across multiple file clicks (matches archive's UX).
- ZIP inline expansion. .zip files have a chevron and act like
folders in the tree. First expand fetches the zip bytes
(server URL or FS handle or parent-zip read), parses with JSZip
(auto-loaded from CDN), and synthesizes the entry tree. Nested
directories within the zip lazy-expand on demand by re-walking
the cached entry list at the right path prefix. Click on a
zip-entry file opens the preview popup with bytes read from
JSZip. Recursive expand-all skips zip archives by design — they
can be very large, and explicit click-to-expand is safer.
- Extension multi-select filter. Toolbar now has a <select
multiple> populated with extensions present in the current
view. Filter is OR-of-selected; combined with the name filter
it's AND-of-both. Folders pass through (so expanding a folder
whose name doesn't match the ext filter still shows its file
children that do match).
