Subject: [PATCH] fix(dock): spans the preview column and loses 20px
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The dock now sits in the preview column (Grid.Column=1), so its left edge is the layers panel's
  right edge instead of starting under the brand column. It is a preview-column control, not a
  full-width footer.
- Expanded height 168 → 148 (112 bays + 36 master strip): the mockup's number read as wasted space
  beneath the 154px scene strip.

Guard: AudioDockLayoutTests pins 148 as the design number, so the constant cannot drift silently.
