ZDDC f01a177b73 feat(html): TIFF and ZIP listing previews + favicon in app headers
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.

Zero Day Document Control (ZDDC)

The Universal Distributed Filing Cabinet

ZDDC is an information management convention plus a small set of single-file HTML tools. Every deliverable's filename encodes its tracking number, revision, status, and title; every transmittal folder is date-prefixed and self-describing. A plain shared folder becomes a fully searchable, auditable archive — no server, no database, no software required to read it.

The name "Zero Day Document Control" comes from the convention itself — adopt it on day zero of a project, with no setup time. The tools are optional interfaces around the structure; the structure works without them.

For end users: https://zddc.varasys.io/ introduces the project, links to all tool channels (stable / beta / alpha), and prints copy-paste shell snippets to install on a self-hosted deployment.

Tools

Tool What it does
Archive Browser Browse, search, and filter a project archive folder. Group by transmittal, export selections as ZIP.
Transmittal Creator Self-contained HTML transmittal records with SHA-256 checksums and optional digital signatures.
Document Classifier Spreadsheet-like bulk-renamer that copy/pastes with Excel and writes back to disk.
Markdown Editor Browser-based markdown editor with YAML front matter, TOC, and direct local file access.

Each tool is published in three channels (stable, beta, alpha) as static files committed under website/releases/, browsable at https://zddc.varasys.io/releases/. Append ?v=alpha, ?v=0.0.4 (exact), ?v=0.0 (latest patch), or ?v=0 (latest minor) to any deployment URL to switch versions for one request. See bootstrap/README.md for the install / pin / audit story.

File-naming convention

The full specification — filename format, tracking numbers, revision rules, status codes, folder naming, and the transmittal workflow — lives at https://zddc.varasys.io/reference.html.

Build & develop

git clone https://codeberg.org/VARASYS/ZDDC.git && cd ZDDC

sh build.sh                              # build all tools (writes to dist/ only)
sh archive/build.sh                      # build one tool

sh archive/build.sh --release            # cut stable; auto-bumps patch from last tag
sh archive/build.sh --release 0.1.0      # explicit version
sh archive/build.sh --release alpha      # cut alpha (mutable channel, no tag)
sh archive/build.sh --release beta       # cut beta

npm install && npx playwright install chromium && npm test    # tests
./dev-server start                       # cache-busting HTTP on :8000

Authoritative build/release docs are in AGENTS.md. Architecture notes (single-file rationale, JS module pattern, security model) are in ARCHITECTURE.md. zddc-server (optional Go HTTP server with ACL and a virtual archive index) is in zddc/README.md. Example Helm charts for deploying zddc-server (production + dev) are under helm/.
