# TASK 61 — The geometry fields share one fixed width

**Status:** ✅ Done — shipped 2026-10-21.

## What it is
The creator (2026-10-21), on Live → Layers → webcam → Properties → **Geometry**:

> the Y and H boxes under webcam properties should be the same width as the X and W boxes
> and those widths should be fixed to accomodate the max number of possible digits
> providing the geometry values

## Why they looked different
The row is a `DockPanel`:

```
[X label][X field][  Y label][Y field]
```

A WPF element **sizes itself to its content** unless it is told otherwise, and in a
`DockPanel` the **last child fills the remaining space**. So the X/W fields (not last)
were as wide as their text ("1920" ≈ 34px) while the Y/H fields (last) stretched to the
full width of the row — two different widths for the same kind of field.

## The fix
- **All four fields carry the same explicit `Width="44"`** — wide enough for the largest
  geometry value (the master frame is 1920×1080 → four digits) **plus a sign** the creator
  may be typing, and no wider.
- **The rows set `LastChildFill="False"`** — otherwise the last field would still stretch
  to the row's width regardless of its own `Width`.

44px = the measured width of `-1920` in the app's font at 11px (≈28px) + the field's
padding (8) + its border (2) + slack.

## The test
`ytLive.Tests/GeometryFieldWidthTests.cs` — the ONE test for this change: the four
fields carry the same **explicit** width (no field sizes itself to its content), and that
width really fits the widest value — measured with WPF's `FormattedText` in the app's own
font (`SystemFonts.MessageFontFamily`) at the field's 11px, plus the padding and border.

## Not done (out of scope, noted in `HANDOFF.md`)
The **web source** block's geometry rows (`Controls/LeftPanel.xaml`, the
`SelectedElement.IsWebSource` panel) have the identical shape and the identical defect —
same fix, one line each, when the creator wants it.
