@@ -31,7 +31,7 @@ Five topics are large enough to have their own deep-dive — read the file befor
 - **`listStyle.ts`** — the named list style (`listStyleName` on the outermost list; nested lists inherit) and the walk resolving every list's effective marker (`data-eff-list-style`, `data-bullet`+`--bullet`, indent, label alignment) from node attr > style level > depth cycle — the style level decides the depth's kind, so a number level numbers a `<ul>` (counter-offset via `counter-reset`, since `<ul>` ignores `start`); `setListStyle` assigns (clearing the subtree's direct marker attrs and retyping each list to its level's kind), `listStyleNameAt` feeds the dropdowns — see `src/lib/styles/CLAUDE.md`.
 - **`link.ts`** — hyperlink mark; owns `Mod-k`, which fires the event `Toolbar.svelte` listens for to open the link dialog. A `#name` href targets a bookmark: `Editor.svelte`'s `handleClick` scrolls to it instead of opening a tab. The `plain` attr (`data-plain`, `editor.css`) suppresses the editor's own blue: Word paints a link through its **Hyperlink character style**, which arrives as an ordinary mark, so every DOCX link is plain and one carrying no style is drawn like the text around it — while LibreOffice paints every ODF `text:a` styled or not (probed), so those never are. The DOCX exporter paints `#0563C1` only on a non-plain link, which is how a round trip tells its own links from a file's.
 - **`comment.ts`** — an annotation on a range of text, a mark like `bookmark`: the whole comment (author, date, body, resolved) rides its attrs, so two runs of one comment merge back together and no second store is needed. `commentRanges(doc)` walks every range (an id split by a paragraph boundary yields several, which is why the commands walk all of them), `comments(doc)` keeps one per id for `CommentsPane.svelte`. A point comment — LibreOffice's, made with nothing selected, written with no `office:name` and no end element — attaches on import to the run before it, else the one after: the editor's comment is a mark and needs a range. A comment carries its **thread** in the same attrs (`replies`, one entry per answer, appended by `replyToComment`): ODF gives an answer its own `office:annotation` naming its comment in `loext:parent-name` (probed) and Word its own `w:comment` tied by `w15:paraIdParent` in commentsExtended.xml, so both importers fold the answers back into the comment they belong to instead of listing them beside it. `commentIdAt(state)` is the comment the selection lies within, which a plugin tints heavier (`pm-comment-active`, skipping a resolved one) and `CommentsPane.svelte`, `ChangeBarLayer.svelte` and `ConnectorLayer.svelte` each mark their own half of. It compares **ranges**, not the marks at the caret: the mark is non-inclusive, so `$pos.marks()` is empty at either end of it — and a click on the pane's card selects exactly that range, which would then match nothing.
-- **`trackChanges.ts`** — the `insertion`/`deletion` marks plus the recording plugin. `appendTransaction` marks whatever a transaction added, and `adjacentInsertion` reuses the id of the run just before it when the author matches, so a typed sentence is one change and not one per keystroke. A delete never reaches the document: `filterTransaction` rejects it and dispatches a mark pass instead (the author's own pending insertion is removed for real, as both word processors do). A **replacement** — typing or pasting over a selection — goes the same way (`replacedRange`), the new content landing after the struck-out text it replaces; recorded as the insertion alone, its other half was simply dropped and a reject lost the original. Every transaction of our own carries the `RECORDING` meta — accept/reject included, or its `tr.delete` would be read as a fresh user deletion and marked up again. **Loading a document carries it too** (`App.svelte`'s `loadContent`, both for a new document and for an import): a `setContent` is one transaction that inserts the whole file, so without the meta an opened document arrives wholly marked as the reader's own insertion, underlined in the author colour. Both word processors record what is typed after an open, never the file. `revisions(doc)` merges adjacent runs of one id, so an export writes one change per id. The **author's colour** is a decoration, not the mark: a mark cannot know the document's other authors, so a plugin walks the revisions, hands out `REVISION_AUTHOR_COLORS` (LibreOffice's own author palette) in order of first appearance and paints `pm-rev-ins`/`-del` + `pm-rev-a<n>`. That span nests *inside* the mark's, so it carries the underline/strikethrough too — drawn by the ancestor it would take the fallback colour. Cached on the doc; the walk is the whole document and `decorations` runs on every view update. `acceptRevision(id)`/`rejectRevision(id)` apply every range of one change, which is what `RevisionsPane.svelte` lists as one row. `revisionIdAt(state)` is the change the selection lies within — the row the pane marks and the margin bar `ChangeBarLayer.svelte` draws heavier — compared by range for the same reason `commentIdAt` is.
+- **`trackChanges.ts`** — the `insertion`/`deletion` marks plus the recording plugin. `appendTransaction` marks whatever a transaction added, and `adjacentInsertion` reuses the id of the run just before it when the author matches, so a typed sentence is one change and not one per keystroke. A delete never reaches the document: `filterTransaction` rejects it and dispatches a mark pass instead (the author's own pending insertion is removed for real, as both word processors do).

Every transaction of our own carries the `RECORDING` meta — accept/reject included, or its `tr.delete` would be read as a fresh user deletion and marked up again. **Loading a document carries it too** (`App.svelte`'s `loadContent`, both for a new document and for an import): a `setContent` is one transaction that inserts the whole file, so without the meta an opened document arrives wholly marked as the reader's own insertion, underlined in the author colour. Both word processors record what is typed after an open, never the file. `revisions(doc)` merges adjacent runs of one id, so an export writes one change per id.

That span nests *inside* the mark's, so it carries the underline/strikethrough too — drawn by the ancestor it would take the fallback colour. Cached on the doc; the walk is the whole document and `decorations` runs on every view update. The `plain` option (from `storage/markup`) drops the decoration entirely where the display mode shows a finished text — and it is part of the cache key, or the set built before the switch would stand. `acceptRevision(id)`/`rejectRevision(id)` apply every range of one change, which is what `RevisionsPane.svelte` lists as one row. `revisionIdAt(state)` is the change the selection lies within — the row the pane marks and the margin bar `ChangeBarLayer.svelte` draws heavier — compared by range for the same reason `commentIdAt` is.
 - **`placeholderField.ts`** — a template placeholder, an inline atom drawn gray as ‹label›: a click selects the whole field (NodeSelection) and typing replaces it; Tab/Shift-Tab from a selected field jump to the next/previous one. Round-trips to ODF `<text:placeholder>` and a tagged DOCX `w:sdt` content control.
 - **`caption.ts`** — a caption is an ordinary paragraph in the `Caption` style (LibreOffice's, probed: 10pt italic, 0.212cm above and below) holding one `sequenceField` atom, its running number. `sequenceFields(doc)` counts one counter per category in document order; the cached `number` attr is what an export writes, and an `appendTransaction` (off the undo stack) plus an `onCreate` pass keep it true — a file's own cached numbers are unreadable wherever the format is not arabic. The counter's name differs per format: ODF `Illustration`/`Table`, Word `Figure`/`Table`, and `ODF_SEQ_CATEGORY` reads both back. The caption paragraph is **boxed to the frame it captions** (`captionPlacement`), so it stands under the picture instead of at the margin: LibreOffice frames picture and caption together, and a loose paragraph carries that over as `indent`/`indentRight` — the frame's own span in the column, measured (`frameSpanCm`), since that span comes from the wrap, the offset and the column, not from one attr. The indent is also what lifts the caption clear of a **side-wrapped** frame: a line with no room beside a float drops below it. It is centred in that box only under a frame that is itself centred; a block with no frame at all has only its own alignment to pass on. `getFrameDebug` reports the same two spans for the debug dump. `CaptionDialog.svelte` (References tab) owns the insert.
 - **`ruby.ts`** — a reading printed over its base (LibreOffice's Format ▸ Asian Phonetic Guide, Word's Phonetic Guide). An inline **atom** carrying both halves, because that is what both formats write: one element holding a base and a reading, edited as a unit (`RubyDialog.svelte`). Rendered as a real `<ruby>`, so the browser sets it. Alignment and position are both products' defaults and are not offered.

 - **`trackChanges.svelte.ts`** — whether the **document** records revisions (`edentext-record-changes`, the key removed when off, as it is by default in both word processors). It travels with the file — ODF `text:track-changes` on the change registry, Word `w:trackRevisions` in settings.xml (both probed against soffice) — so an import adopts the file's flag and a new document starts off; only the open document's state lives under the key. A reactive singleton because the extension reads it on every transaction while the Review tab flips it; the recorded changes themselves live in the document, on the marks.
 - **`lineNumbering.ts`** — numbers in the left margin (`edentext-line-numbering`, the key removed when off, as it is by default in both word processors). ODF keeps one `<text:linenumbering-configuration>` in `office:styles`, Word a `<w:lnNumType>` per `w:sectPr` (probed). `LineNumberLayer.svelte` measures the lines: CSS exposes no line boxes, so a Range per block is taken and its distinct client-rect tops are the lines.
 - **`printMarkup.svelte.ts`** — whether a printout carries the review markup (`edentext-print-markup`, the key removed at its **on** default, so it is the off state that is stored — the switch both word processors offer). A reactive singleton like `trackChanges.svelte.ts`: the Review tab flips it, all three export paths read it. What it governs lives in `export/reviewPrint.ts`.
+- **`markup.svelte.ts`** — the whole review view. The mode (`edentext-markup-mode`, absent at `all`) is Word's four steps — *all* (every change marked up), *simple* and *none* (the final text, the second without bars, cards or lists), *original* (the text before the changes). Per kind it holds whether it shows (`edentext-markup-comments`, `edentext-markup-changes`) and **where** its cards go (`edentext-markup-comment-place`, `edentext-markup-change-place`, absent at `balloons`) — beside the line or in the pane, which is why no separate pane flag exists any more. The two are tied: picking a mode carries both kinds with it, and switching a kind on lifts a mode that hides everything back to *all*, so no button is left claiming what the page does not show. `markupView()` folds it into what the page and the layers act on, read once instead of re-derived at every call site; `markupAttrs()` is the same view as `.paper` attributes, for the print path that builds its page from scratch. Both formats keep the choice out of the file — it is a view, like zoom.
 - **`foldMarks.ts`** — fold + punch marks in the left margin (`edentext-fold-marks`, the key removed when off; neither word processor prints any by default). The DIN 5008 positions (87/192mm folds, 148.5mm punch) are this module's constants; `FoldMarkLayer.svelte` draws them per page — the folds on **both** edges (both hands find the crease), the punch mark only left, where the pages are filed. They export as named lines (`EdenFoldMark*`) in the master page's header — the one place that repeats on every page, where LibreOffice's own DIN templates keep them — ODF as page-relative `<draw:line>`s, DOCX as VML `<v:line>`s; both importers read the names back into the flag and never into the zone's content.
 - **`pageOrientation.ts`** — `'portrait' | 'landscape'`. `applyOrientationVars` sets `--user-page-{width,height}`; landscape swaps the A4 dimensions (matching odf-kit's automatic swap).
