Markdown preview pane now surfaces YAML front-matter above the TOC as a
key/value list (definition list), so engineering documents with header
metadata (title, revision, status, etc.) show their identity at a glance
without opening the file in mdedit. Front-matter parsing handles both
scalar and array values; arrays render as comma-joined.
TOC pane is now resizable (4px col-resize handle on its left edge);
preserves the user's chosen width across re-renders inside a single
session.
mdedit welcome banner moved inside #welcome-screen so the "browse opens
md in this same editor" callout only shows when no file is open — it
was previously visible in every state which was noisy.
archive.spec.js: wait for #filePreviewToggle to be attached before
clicking, fixing a Playwright flake where the preview button hadn't
mounted yet.

Reshape browse from "tree-as-table with popup preview" into a unified
file-experience tool with three layered behaviors:
Phase A — Two-pane shell
Phase B — Markdown plugin (Toast UI inline)
Phase C — Grid mode (classifier workflow)
Phase D — Deprecation banners on standalone classifier + mdedit
= Phase A: two-pane shell + lightweight preview plugins =
Browse's table view becomes a tree-pane on the left + preview-pane on
the right with a draggable resizer. Click a folder → expand inline.
Click a file → render in the right pane. The previous popup window
becomes an explicit "⤴ Pop out" button in the right-pane header for
users with a second monitor.
Preview rendering reuses shared/preview-lib.js (PDF iframe, image
<img>, TIFF, ZIP listing, text <pre>). Unknown types show a download
link. browse/js/preview.js refactored into renderInline (default) +
renderInPopup (Pop out button); both share the same plugin
dispatch logic.
Filter rows were already removed earlier this session. Sort columns
likewise — the tree is alphabetical by default; the underlying
setSort API still exists for future re-introduction.
= Phase B: markdown plugin =
New browse/js/preview-markdown.js: when a .md or .markdown file is
clicked, the right pane mounts a Toast UI editor (initial-value =
file contents) with a small toolbar containing Save + dirty indicator
+ status text. Save sends PUT through the file API for server-mode
files; non-server sources are read-only for now (deferred to a
follow-up that wires zddc-source.js writes too). Ctrl+S / Cmd+S
inside the editor saves.
Toast UI Editor (~700 KB JS + ~160 KB CSS) was previously bundled
only in mdedit/vendor/. Moved to shared/vendor/ so browse and mdedit
both pull from one location.
= Phase C: grid mode =
View-mode toggle [Browse | Grid] in the toolbar. Grid mode loads the
classifier tool as an iframe scoped to the current directory (server
mode at working/staging/incoming locations) — classifier's full
bulk-rename workflow without leaving browse. v1 implementation; a
future iteration could bundle classifier's modules directly into
browse for tighter integration. Hostile cases (file:// origin, paths
outside working/staging/incoming) show a friendly explanation
instead of a blank iframe.
new browse/js/grid.js handles the activation logic.
= Phase D: deprecation banners =
mdedit and classifier standalones gain a "this tool is being absorbed
into Browse" advisory banner. Both standalones remain fully
functional and continue to ship — they're useful for offline single-
file editing and air-gapped environments. The banner just points
users toward the unified browse experience.
= Files =
+ browse/js/preview-markdown.js (markdown plugin)
+ browse/js/grid.js (grid-mode plugin)
M browse/template.html (two-pane layout, view toggle, banners)
M browse/css/tree.css (two-pane CSS, replaces table styles)
M browse/js/init.js (state additions: selectedId, viewMode)
M browse/js/tree.js (rowHtml: <tr>+<td> → <div>)
M browse/js/preview.js (renderInline / renderInPopup split)
M browse/js/events.js (toggle wiring, resizer, click handlers
adapted from <table> to <div>)
M browse/build.sh (Toast UI vendor + new modules)
R mdedit/vendor/toastui-* → shared/vendor/ (one bundle, two tools)
M mdedit/build.sh (paths)
M mdedit/template.html (deprecation banner)
M classifier/template.html (deprecation banner)
M tests/browse.spec.js (selectors updated for new layout +
new "click file → preview" test)
Bundle sizes after this commit:
browse: ~1020 KB (was ~290 KB; added Toast UI ~700 KB)
classifier: ~1470 KB (unchanged from prior baseline)
mdedit: ~2140 KB (unchanged; vendor location moved but not added)
What's deferred:
- TOC + front-matter pane in browse's markdown plugin (mdedit has
these; browse v1 uses just the editor).
- FS-API writes from browse's markdown plugin (server PUT works).
- Classifier modules bundled directly into browse (v1 uses iframe).
- Sort UI in the new tree (model still supports it; no widget yet).

Six inline style="" attributes in archive, browse, mdedit templates
moved into stylesheets:
- The font-size:1.1rem override on #refreshHeaderBtn (three tools) is
now a single rule in shared/base.css — the refresh ⟳ glyph genuinely
reads smaller than ◐ / ?, so the rule lives next to the existing
shared icon-button block.
- The flex-start justify-content + select-all margin on archive's
Revisions column header become a .th-content--start variant +
.select-all-checkbox class in archive/css/table.css.
- The 450px initial width + 200px min-width on mdedit's #file-nav move
into mdedit/css/base.css; the runtime resizer continues to override
via inline style.width when the user drags.
No visual change — the output is exactly equivalent.

Bring every tool's header in line with archive's pattern:
[logo] [title] [version] [Add Local Directory] [⟳] ............... [◐] [?]
------------- header-left --------------- ----- header-right -
Changes per tool:
* browse: rename "Select Directory" → "Add Local Directory"; add the
red-non-stable wrap to the build label (was missing); add a help
panel + bundle shared/help.js.
* classifier: rename selectDirectoryBtn → addDirectoryBtn,
refreshBtn → refreshHeaderBtn for consistency. Update all JS
callers and welcome-screen copy to the new label.
* mdedit: same id rename. Move the previously-in-pane refresh
button into the header. Stop renaming the dir button to
"Directory: <name>" once a folder is loaded — instead use the
shared btn--subtle variant to de-emphasize while keeping the
standard label.
* transmittal: convert non-standard <div class="app-header"> with
spacer/icons containers to <header class="app-header"> with the
canonical header-left/header-right pair. Move the publish split-
button into header-left (Transmittal-specific primary action).
Remove dead .app-header__spacer/__icons/header-icon-btn CSS now
that nothing references those classes.
* landing, form: add help-btn + help-panel + bundle shared/help.js.
Each panel is tool-specific (project picker docs for landing,
schema-driven form docs for form).
Cross-cutting:
* shared/base.css: promote .btn--subtle from browse/css/tree.css
so any tool with an online mode can de-emphasize Add Local
Directory consistently.
Verified all 7 tools in headless Chromium: header structure correct,
build label red on non-stable cuts, help panel opens + closes via
button + Esc.
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.

Bundles a stretch of in-progress work across the SPA tools so the
tree returns to a coherent shippable state ahead of cutting a new
zddc-server stable image:
- landing: substantial rework of the project picker (sortable/filterable
table, presets refactor, ?projects= filter, ?v= channel propagation,
loading/error states)
- archive: presets cleanup, source.js refactor, filtering/url-state
alignment with the landing page
- mdedit: file-system module split, resizer, file-tree improvements,
base/toc styling tweaks
- transmittal/classifier: small template touch-ups for shared chrome
- shared: build-lib.sh helpers, new favicon.svg
- bootstrap, build.sh: pick up the channel-aware install/track zip
generation
- tests: new landing.spec.js, expanded archive/mdedit/build-label specs
- docs: CLAUDE.md picks up the zddc-server section and freshens the
alpha-build exception note
- regenerated artifacts: install.zip, track-{alpha,beta,stable}.zip,
*_alpha.html — these are produced by `sh build.sh` and per project
convention are committed alongside the source changes
