Remove the face carousel — one card presentation

03's resettlement reverses the pathfinder carry-over: the
selection-keyed dual presentation proved undesirable, so a card has one
presentation — selection changes styling, never geometry, and the
masonry never reflows on click. Deleted the carousel view (page dots,
glass underlay, scroll-tick monitor), the QuickLook thumbnail cache
(sole consumer), the pure paging/suppression rules, and the
sole-selected animation key — Motion now keys transactions on the
search query and the drop proposal only. The attachment chip stays as
the face's whole attachment story; viewing media is the card window's
job. No carousel state had leaked beyond the view layer.

 - **Live store** — every open board is one shared, watched, in-memory snapshot: an FSEvents folder watcher (debounced, `.git`-filtered, origin-reconciling) drives whole-tree reloads with a generation guard and single-flight coalescing; write brackets suppress self-echo; a file-identity-keyed store registry refcounts stores and watchers across windows and absorbs root renames via bookmark re-resolution (a vanished root locks the board and watches for its return); plus the board registry (recents, bookmarks, cached counts), the banner center's single precedence order, the dirty-buffer guard, and transient UI state.
 - **Window architecture** — the three window types and their lifecycle: a welcome window (below), one board window per root (per-board frame memory, repositioned onto a live screen), and at-most-one card window per card (last-used size, cascaded; follows its card across lanes; dismisses on delete, tombstone, or cross-board move). Closing a board window or quitting runs one strict close flush — card sessions end, pending work drains, the registry is stamped — before the store tears down; launch restores the boards whose open-now flags survived quit (or crash), a preference gating only whether the flags are consulted.
 - **The board** — every lane always on screen, the window's width dividing across the lanes' width units with no horizontal scroll: cards flow into as many interior masonry columns as a lane is wide, a right-edge drag resizes between whole units by growing the *window* (snapping at the gap with release hysteresis, hard-stopping at the screen with rubber-band feedback), and ⌥⌘→/⌥⌘← re-divide the existing width instead. Lane chrome is a per-lane SF Symbol (unknown names fall back leniently), title or untitled placeholder, a card-count badge that counts exactly what's rendered, and a new-card button — the whole title bar doubling as the drag surface, a plain click selecting the lane and movement carrying it away.
-- **Card faces** — a card reads as a leading SF Symbol, its title (or a quiet untitled placeholder), and a quiet paperclip when it has attachments — title-only by design, no body excerpt. Colour is an edge accent rather than a fill: `background` paints a stripe down the card's left edge and `iconColor` tints the symbol, both written as a kebab-case palette name (12 icon tints, 12 backgrounds) or a `#RRGGBB[AA]` hex. Everything degrades rather than complains — an unreadable colour simply doesn't paint, and the value stays on disk exactly as written. Each card's snapshot carries its attachment names, listed flat and in Finder order (top-level files only; subfolders, hidden files, and symlinks are preserved but never surfaced).
-
-- **The attachment carousel** — select a single card with files and its face expands in place into a paged carousel, one page per attachment in Finder order: a QuickLook thumbnail for anything previewable, the file's Finder icon while one is being made and instead of one for anything that isn't, and page dots on a glass underlay (solid under Reduce Transparency). Trackpad pan, a click on a dot, and a scroll-wheel tick all page it. It is single-selection only — add a second card to the selection and every carousel folds away — and a rubber band in flight suppresses it outright, so sweeping a band across a row of cards never flickers one open. The expansion animates under a transaction keyed on the sole-selected card and nothing broader, so multi-select churn and the band itself animate nothing at all; Reduce Motion makes the growth instant and leaves the fade. Thumbnails are cached per board window against each file's own bytes, so reselecting a card costs nothing while a file rewritten under the app regenerates.

A card has one presentation: selection changes only its styling, never its geometry, so the masonry never reflows on a click — the paperclip chip is the face's whole attachment story, and viewing the files themselves is the card window's job.
 - **Creating and renaming** — New Card (⌘N) files into the selected card's lane immediately after it, a selected lane's bottom, or the last-active lane, opening a focused pseudo-card that exists nowhere on disk until its title commits (Return commits and re-selects the lane, ⌘↩ also opens the card window, Escape or clicking away discards, and a failed create discards rather than waiting for a card that can't arrive). Inline rename — Return on a card, Board ▸ Rename for either kind — tracks its target by UUID, so a foreign move mid-edit is invisible and a tombstone or deletion discards the edit silently; committing empty removes the `title` key rather than writing a blank one. New Lane is ⇧⌘N. Every mutating command disables while an editor holds the keyboard and under the read-only lock.
 
-- **Drag & drop** — cards, lanes and trash rows all travel as real system drag sessions, so a drag crosses window boundaries, shows the system's own copy badge, and carries a full-size replica of what it picked up. A dashed shadow sits at the exact landing spot and the board reflows to make room; the proposal is pure geometry over an analytically reconstructed resting layout — never measured mid-animation frames — so the shadow is stable rather than jittery, and a lane only reflows once the cursor reaches where the dragged run would actually land, holding its last proposal across the ambiguous stretch in between. Dragging any member of a multi-selection drags the whole selection: N contiguous shadows, one insertion point, landing in flatten order. Locality picks the default the way Finder's volumes do — within a board a drag moves, between boards it copies, with ⌥ forcing copy and ⌘ forcing move and the badge tracking live as the cursor crosses a boundary; a lane reordering inside its own board ignores ⌥ entirely, and a lane copy strips tombstoned cards while a lane move carries them whole. Dragging a trash row onto a lane restores it at the drop position, ⌥ copies it out live instead, and dropping it on another board follows the same copy-out grammar. Lanes taller than their viewport autoscroll from either edge, re-resolving the landing spot on every step so a stationary cursor still lands where the shadow shows. A foreign edit mid-drag re-grounds the drag rather than corrupting the drop: the zones re-derive against each new snapshot, a proposal whose lane was deleted withdraws and a release with none simply cancels, and a drag whose items all vanish dissolves itself. At release the board keeps drawing the dropped arrangement until the write round-trips through the watcher, so nothing snaps back for a frame; every drop is one write bracket — one reload, one commit — whatever the set's size. Files dragged in from Finder join the same dispatch: dropped on a card they copy into its `attachments/` (any type, multi-file, Finder-style renames on collision, the card highlighting while hovered), dropped on lane empty space they become one card per file — titled with the filename minus its extension, that file attached, landing at the drop position with a shadow per card. Tombstoned surfaces are inert to them, and a read-only board or an open inline editor refuses them outright.

Dragging a trash row onto a lane restores it at the drop position, ⌥ copies it out live instead, and dropping it on another board follows the same copy-out grammar. The same gesture runs the other way: dropping a live card on the shown trash deletes it, exactly as ⌫ would, with the shadow always taking the topmost row — which the newest-first sort makes honest rather than arbitrary. Lanes aren't deliverable that way, a foreign board's card isn't, and ⌥ isn't, since copying into the trash isn't a thing.

 - **The keyboard** — the board is fully operable without the mouse, and every board function has a menu item. Arrows walk to the nearest card in the direction — across a lane's interior masonry columns, across lanes, and into and out of the shown trash — with ⇧-arrows extending the range from the anchor and stopping dead at the liveness and card/lane-entry boundaries rather than silently reaching past them. ⌥-arrows jump: ⌥↑/⌥↓ to the lane's first/last card, ⌥←/⌥→ to the first/last lane (⌥→ reaching the trash when it's shown), and a second ⌥↑ on a lane's first card escalates into selecting the lane itself — the one keyboard entry to lane selection, from which ←/→ move between lanes, ↓ descends back into the cards, and an empty selection seeds at the first lane's first card so an arrow from nothing always means the same thing. The selection scrolls itself into view. The Board menu carries the rest: Open Card (⌘↩) — the one command that stays live mid-edit, committing the title and opening the window — Move Up/Move Down (⌥⌘↑/⌥⌘↓), which sort within a lane in logical order and gather a scattered selection into a block behind its first card on the first press, and Move Left/Move Right (⌘←/⌘→), which slide a selected lane one slot and never into the trash. Deleting picks the successor sibling Finder-style, so repeated ⌫ walks down a lane; an external deletion deliberately doesn't.

 - **Styling** — one style editor serves every anchor: a background grid of the twelve palette wells behind a leading None well that *removes* the key, and a curated grid of five dozen kanban-relevant SF Symbols behind a leading level-default well that does the same. It is selection-aware (the selected cards or lanes; the board with nothing selected) and states the current value per dimension across the whole target set — agreement selects a well, disagreement reads "—", and a hand-written hex or uncurated symbol states itself verbatim outside the grids, replaced by any well you choose. A batch applies as one bracketed commit that skips every target already carrying the value, and the open editor tracks its targets live: one deleted out from under it leaves the set, and the last one closes the editor rather than quietly retargeting the board. Reached from Board ▸ Style… (⌥⌘S) or a card's or lane's context menu, where a compact row of app-wide recent colours recolours in one click and a lane's menu also carries its width stepper. Colour renders at all three levels — a card's `background` as a left-edge stripe, a lane's as a full-width band along its top edge, the board's as the window's content background — each painting nothing at all when the value doesn't resolve, bytes on disk untouched.
 
-- **The trash** — deletion is two-stage and Finder-shaped. File ▸ Delete (⌘⌫, or a plain ⌫) tombstones the selection in place — cards or lanes, one bracketed write for the whole batch — and View ▸ Show Trash reveals a trailing quasi-lane where tombstoned items live. It is a pure view: nothing moves on disk, so Put Back is byte-perfect and returns an item to its old position. The column takes exactly one width unit while shown, so showing it re-divides the window rather than resizing it. Its order is fully deterministic (newest deletion first, ties by folder name, an unreadable timestamp sorting oldest) and its ancestor walk is absolute — a tombstoned lane is one entry subsuming everything beneath it, its count naming the cards Put Back would return, so recovering a separately deleted card inside it is deliberately two steps. Drag a row out onto any lane to restore it there. Purging is Delete Immediately (⌥⌘⌫) and Empty Trash… (⇧⌘⌫), each confirmed where the loss is real and named by count; Empty Trash always covers the whole trash, never just what a filter is showing. Nothing edit-shaped — Open, Rename, Style… — applies to a tombstoned selection, and a selection never mixes trashed with live.

 - **Live search** — the board window's toolbar carries one item, a search field (Edit ▸ Find, ⌘F), and typing in it filters the board as you type: a card stays when its title *or* its body contains the query, case- and diacritic-insensitively (so `resume` finds "Résumé"), and everything else animates out under one gentle spring while the survivors reflow. Scope is title and body only — attachment filenames are deliberately not searched. The filter is the single source of truth for what's on the board rather than a highlight over it: the masonry, each lane's count badge, drop zones, the rubber band, ⇧-ranges, Select All, arrow navigation and the ⌥-jumps all read it, and the shown trash filters like any other lane, its card rows and lane rows each by their own text. Nothing invisible stays selected — a card the query hides leaves the selection the moment it goes, and so does one an agent edits out of the match while you search. The field is a control, not an editor: board commands stay live and act on the selection while you type (⌘N included, which clears the search first so a new card is never born invisible), only ⌘←/⌘→ and ⌥⌘←/⌥⌘→ stand down so they stay caret chords, plain ⌫ edits the query while ⌘⌫ still deletes the selection, and Return is swallowed because a live filter has nothing to submit. Tab hands the keyboard to the board with the query intact. Escape steps out one layer per press — a non-empty field clears, an empty one returns focus to the board, and a board-focused Escape under an active search clears it before it means deselect. A rename is deliberately not a carve-out: rename a card out of the match during a search and it animates away exactly as an agent's edit would.
