HTML files in the file previewer (archive, transmittal, classifier
popups) were dispatched to the text renderer because 'html'/'htm'
are in shared/preview-lib.js's TEXT_EXTENSIONS (which is shared with
the syntax-highlighting code path). Result: opening an .html file in
preview showed its source as a <pre> block, not the rendered page.
Fix in each tool's popup builder + dispatcher:
- Add 'html' / 'htm' to the iframe branch (alongside pdf), so the
popup ships an <iframe src=blob:...> instead of an empty
#previewContent div. The blob's MIME type from getMimeType()
is already 'text/html', so the browser renders natively.
- Skip the text-render dispatch for html/htm (the iframe is enough).
- Add to the HTML iframe so an arbitrary archived
HTML file cannot run scripts, navigate top, submit forms, or
open popups in the popup-window's origin. PDFs don't need this
since the browser's PDF viewer is sandboxed natively.
classifier/js/preview.js uses a getPreviewType() switch instead of
chained ifs; adds 'html' as its own preview type (checked BEFORE
'text' since html is in TEXT_EXTENSIONS).
mdedit already handled HTML specially (file-tree.js has an isHtml
check); no change there.
TIFF was already rendered via the shared zddc.preview.renderTiff
canvas viewer in all four tools — no change needed for that path.
If TIFF preview appears broken on the live prod server, that's the
v0.0.9-alpha-baked-in image; the fresh stable redeploy fixes it.
Adds shared/preview-lib.js with two cross-tool renderers:
- renderTiff (UTIF.js, lazy-loaded from CDN; PDF-style toolbar with
page nav, zoom, fit-width/fit-page; multi-page TIFFs decode lazily)
- renderZipListing (JSZip; sortable name/size/modified table, sticky
header, host-grouped paths)
Wired into the four tools that have a preview surface (archive, classifier,
mdedit, transmittal). Cross-document compatible so the same renderer works
for popup-window tools (archive/classifier/transmittal) and inline tools
(mdedit). Archive previously had no image branch at all — now previews
JPG/PNG/GIF/WebP/BMP/SVG natively, plus TIFF via UTIF, plus the ZIP listing.
Adds the dark-blue rounded-square favicon to each app's header (left of
the title) and to the website navigation. Single inline SVG, sized via
.app-header__logo (in shared/base.css) for tools and .brand-logo (in
website/css/style.css) for the website. Self-contained — the SVG carries
its own background, no wrapper styling needed.

ZDDC — Zero Day Document Control. A file-naming convention plus five
single-file HTML tools (archive, transmittal, classifier, mdedit,
landing) and an optional Go HTTP server (zddc-server) with ACL and a
virtual archive index. Self-contained, offline-capable, dependency-free.
See README.md for an overview, AGENTS.md and ARCHITECTURE.md for the
build/release/architecture detail, bootstrap/README.md for the
two-level deployment install pattern, and zddc/README.md for the
HTTP server.
