Switching the preview garment cleared the scene (print lost), and
re-loading a print used the canvas's hard-coded centred default instead
of the selected template.
- template_panel: add apply_current() to re-emit the selected template
for the current garment/print sizes and sync _current_state.
- main_window: remember the current print path, restore it after a
garment switch, and call apply_current() after garment/print changes
so the selected template stays sticky. Fine-tuned items are unaffected.
- Also feed template_applied into export_panel.set_transform to keep the
single-export transform in sync.
Docs: record the sticky-template rule (PRD 6.6).

Material list:
- Switch asset list from one-per-row to a wrapping thumbnail grid
(IconMode cards: thumbnail + corner checkbox + elided name, subfolder
moved to tooltip).
Templates:
- Template.to_transform_state now contains-fits the print inside the
target box by the print's native aspect ratio (no stretch); falls back
to the box when print size is unknown.
- Feed print native size into template_panel for aspect-aware fitting.
- Shrink built-in template boxes to realistic print proportions.
UI hierarchy:
- Promote 打开文件夹 buttons to primary (filled accent).
- Add inline 归零 (reset angle) and a 重置位置/尺寸/角度 button to the
transform panel; wire it to re-apply the selected template.
- Hide 保存 for built-in templates instead of leaving it greyed.
Docs: record template box/contain behavior (PRD) and the grid layout,
button hierarchy, and reset/save-visibility rules (UI design).
Tests: add 3 aspect-fit cases for to_transform_state.

TransformPanel provides the right-panel parameter editing section:
- Position: X/Y QDoubleSpinBox (range ±99999 px, 0.1 step)
- Size: Width/Height QDoubleSpinBox (min 10 px) + 锁定宽高比例 checkbox
- When locked and width changes, height is auto-updated to maintain ratio
- When locked and height changes, width is auto-updated to maintain ratio
- Locking captures the current ratio at that moment
- Rotation: angle QDoubleSpinBox + 左旋 90° / 右旋 90° buttons
Signal-loop prevention:
- set_transform() sets self._updating = True and blockSignals on all inputs
before updating values, preventing valueChanged from re-firing _emit()
- _on_width_changed/_on_height_changed also blockSignals on the companion
spinbox when adjusting for aspect ratio to avoid double emission
Public API:
- set_transform(TransformState): programmatic update, no signal emitted
- get_transform() -> TransformState: read current inputs
- transform_changed signal: emitted whenever user edits any input

Replace placeholder ImageCanvas with full QGraphicsView/QGraphicsScene editor:
Layout: ImageCanvas(QWidget) = top bar + _CanvasView(QGraphicsView) + hint bar
Top bar: garment/print filenames, mode buttons (移动/缩放/旋转, context-aware),
zoom controls (−/% label/+, scroll wheel).
_CanvasView:
- drawBackground: checkerboard in garment area, gray outside
- wheelEvent: zoom in/out anchored at cursor
- mousePressEvent/mouseMoveEvent/mouseReleaseEvent: delegate to ImageCanvas
Scene (1:1 with garment pixel coords):
- garment QGraphicsPixmapItem at (0,0), not interactive
- print QGraphicsPixmapItem positioned/rotated from TransformState
- cosmetic selection rect (blue, 1.5px)
- 4 corner handles (white circle, blue border) for scaling
- rotation arm (dashed) + handle (blue circle) above top-center
Interaction:
- Hit test: rotation handle > corner handles > print body (priority order)
- Move: delta in scene coords added to TransformState.x/y
- Scale: _scene_to_local_xy() maps mouse to item local coords, computes
new size keeping opposite corner fixed (_do_scale); supports aspect
ratio lock via Shift or keep_aspect_ratio flag; correct with rotation
- Rotate: atan2(mouse - center) + angle offset at press
Coordinate helpers (static):
- _local_to_scene_xy(lx, ly, state): item-local → scene
- _scene_to_local_xy(sx, sy, state): scene → item-local (inverse rotation)
Both use TransformState snapshot, not live item state, to avoid stale-pixmap issues.
transform_changed signal fires on mouse release with final TransformState.
Preview zoom changes only QGraphicsView transform; TransformState is unaffected.

Expand MainWindow from placeholder to full structural layout:
- Header bar: app name, version label, settings button
- Flow tab bar (QTabBar): tabs 2/3 disabled, click redirects to status bar message
- Work area (QSplitter): ImageListPanel (left 374px) | ImageCanvas (center, stretch) | right scroll with TemplatePanel/TransformPanel/ExportPanel (318px)
- Queue panel (188px, collapsible ▲/▼ toggle)
- QStatusBar with Windows-style styling
Applies color/font spec from docs/07-ui-design.md §10.
No business logic in main_window.py; panel stubs remain for tasks 8–13.
