Preview, stacked (over/under): title, the rendered body and the comment
thread now stack in one continuous document with one scroll, instead of
the fixed ≈3:2 split with each pane keeping its own. Edit mode keeps the
split unchanged (an editor needs a stable scroll of its own), and the
beside mount is untouched.
CardBodySurface gains a `scrolls` flag: false switches off the hosted
NSScrollView's scroller and elasticity and reports the NSTextView's own
height for the proposed width via `sizeThatFits`, the layout-manager
height-fit trick CommentBodyView already uses one level up. CardCommentsPane
gains an `embeddedProxy`: supplied, it renders the same header, find bar,
rows and composer without wrapping them in a second ScrollView, driving
scrollTo off the outer document's proxy instead of its own. CardWindowView
composes the two behind a new pure predicate, CommentsMount.showsContinuousDocument(mode:),
tested in CardCommentsLayoutTests.
The continuous↔split swap within stacked mount is a genuine remount of the
body pane (two independent scrolls can't become one shared scroll by
reconfiguration) — the same accepted cost the raw-source outlet already
takes elsewhere in this window. No new animation on that swap, matching
this file's existing precedent (the raw-source swap and the beside↔stacked
mount switch are both instant cuts today). Decisions recorded on the card's
thread, flagged for owner review where they're user-visible.

The card window recomposes into three componentized panes (body,
comments, attributes) with two mounts — beside or body-over-comments
at ~3:2 — behind View ▸ Comments Beside Body. View ▸ Show Comments is
one persisted app-wide bit, no content-derived auto-show; File ▸ Add
Comment flips it on and focuses the composer. The thread renders
author lines, edited markers, card-subset Markdown bodies, and
read-only Quick Look chips under a count header with the sort-
direction control. The composer edits comments/.draft/ on the slow
cadence (blur, close, quit, ~30s interval), Escape only moves focus,
⌘↩ posts. Inline edit is a body-edit session in miniature: 700ms
debounce, Save/⌘↩ commits, Cancel and Escape revert to session-start
bytes, close flushes. File drops within either authoring surface
carve out of the window-wide card default into that surface's
attachments/; paperclips cover the no-drag path. Close flush runs
inline flush, then draft save, then the comments/.trash purge;
open sweeps crash residue.
