Comments, phase 2 — the pane, the composer, and the inline session

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.
