Docs: record the zoom box as TASK 52 and fix the task-numbering drift (Unit: zoom docs)
The zoom feature shipped without a task record while its index rows carried the "TASK 51" label — which belongs to the webcam background effects (Remove + Blur). For an honest catalogue and handoff: - TASKS/task-52-zoom-box.md: feature provenance (creator-requested), the three 2026-10-08 corrections (loupe -> anchored capture over the full composite drawn last -> never show the dim shading), shapes, implementation map, tests, DONE. - TASKS.md: row 52 added (shipped); row 51 reworded — unblocked now that the zoom build shipped. - TASK 51 -> TASK 52 in Models/index.md, ViewModels/index.md, and the two code comments that pointed at the zoom as "TASK 51". - HANDOFF.md: pre-push readiness notes (5 commits ahead, push-safe).

Right-clicking the live preview anchors a FIXED **capture window** (the box/2 region centred on the click) and parks a movable **2x magnifier**. The box shows a live always-on 2x view of the anchored capture; **dragging moves only the box — `CaptureX/Y` are deliberately untouched in `UpdateZoomMove`** (creator ruling). Each shape is centred on the click and clamped independently (box to the master, capture to box/2 windows): Circle = square, VerticalRectangle = 9:16, HorizontalRectangle = **4:3** (w=h·4/3 with h=0.7·1080; NOT 16:9 — first cut read as a square). The transient `ZoomSceneElement` mirrors box + capture; the output compositor draws it **LAST (layer n+1)** from the already-composed frame (`SceneCompositor.BlitZoom`→`ZoomMagnifier`) so it captures EVERY layer. No per-frame builder/cache — the resolver case that built `ZoomFrameBuilder` frames was removed. `BuildCompositorOptions` (internal = test seam) always returns the tier crop — the box is never the crop source. |
