2026-07-20	grid: j/k move the cursor down/up one row; stop blanking thumbnails on nav	Paul Buetow
	_on_nav_changed rebuilt every cell on every navigator "changed" signal, so a single h/l/j/k press destroyed and recreated all 613 GtkPicture cells (each re-requesting its thumbnail) and the grid flashed blank. Now it only does a full ggaze_grid_refresh when the file count actually changed (rescan/trash/move); a mere current/mark change just refreshes mark badges in place and re-selects the cursor. Add j/k row navigation: ggaze_grid_move_cursor finds the cell in the adjacent row closest to the current column via gtk_widget_compute_bounds and sets navigator.current to it (so the header / large-view preview track the move and the light nav-changed path re-selects it). h/l stay linear via the existing global win.next/prev. Also document j/k in the ? shortcuts overlay.
2026-07-20	grid: mark multi-selection (v / Ctrl+a / Esc) and a ? shortcuts overlay	Paul Buetow
	The navigator already had a mark API and the grid rendered mark badges, but nothing could set marks — so multi-file ops (D, Ctrl+c, m) only ever acted on the single current image. Wire up marking in the UI: - v toggles a mark on the highlighted grid cell (or the current image in large view). navigator_toggle_mark does not emit "changed", so the cell's badge is updated in place via ggaze_grid_update_mark_badge (no reflow / re-decode). - Ctrl+a marks all; Esc now clears marks first (contextual), then keeps its existing back/quit behavior. - The window title appends "N marked" so multi-selection is visible. - A GtkCssProvider styles .ggaze-marked (accent border + tint) — the class was set but had no styling, so badges were invisible. Also add a ? -> win.shortcuts action that presents a GtkShortcutsWindow (grouped: navigation, view, selection, files, zoom) built from an inline GtkBuilder UI string, transient to the window. tests/test_shortcut.c full-table test updated for the three new bindings (v, Ctrl+a, ?) -> 23 rows, 19 actions.
2026-07-20	grid: sync flowbox selection to navigator.current on Enter/t (cu0)	Paul Buetow
	Arrow-key navigation in the grid moved the GtkFlowBox selection but never updated navigator.current, so Enter (and toggling to large with t) opened the stale current image instead of the highlighted one. _on_flow_key emitted the activate signal directly without syncing, unlike the double-click path (_on_child_activated) which does sync. Add ggaze_grid_sync_current(): reads the selected flowbox child and calls navigator_set_current_file. Call it from _on_flow_key before emitting activate, and from _action_toggle_view's grid→large branch (then load the now-current image). Mirrors the existing double-click sync.
2026-07-13	gridcull: thumbnail TMS cache, grid view, trash, window d/D/u/t (jt0)	Paul Buetow
	M7 (task jt0): thumbnail cache + grid view + trash. - src/trash.{c,h}: ./Trash bin (lazy create, collision suffix -1/-2, restore_last for u undo, permanent delete for D). Plain-C, unit-tested. - src/thumbnail.{c,h}: freedesktop TMS cache (normal/large/x-large buckets, md5(URI) key, Thumb::URI/MTime/Size, mtime verify). Async GTask worker with GCancellable so the grid can cancel pending requests on dispose. - src/gridview.{c,h}: GgazeGrid (GtkWidget wrapping GtkFlowBox): one cell per navigator file, lazy thumbnail decode on realize, +/- resize 64-512, dim removed cells, mark badges, Enter/double-click → 'activate' signal, cursor sync. ggaze_grid_detach() breaks the nav ref before dispose. - src/navigator.{c,h}: removed set (mark_removed/is_removed/unmark_removed); _relist preserves removed items (stay dimmed even if absent from disk); get_remaining = count - removed_count. - src/window.c: d (trash+mark_removed+advance), D (permanent delete, confirm dialog if >1 marked), u (restore_last+rescan), t (toggle grid/large), +/- (viewer zoom in large / grid resize). Header counter uses remaining. - src/shortcuts.c: d/D/u/t/+/= bindings added. - tests: unit test_trash + test_thumbnail, integration test_grid_cull (grid count + trash/undo + ./sample-images 613-cell grid). 13/13 green, ASan clean. Fixed: grid dispose UAF (detach before nav freed), g_file_get_basename leak, test p_plain lifetime, thumbnail async-cancellable for clean dispose, test grid-toggle avoiding async-thumbnail drain issues.
