/* ============================================================
   BUILD-MODE LAYOUT (Besiege / Kerbal VAB / Aviassembly)
   ============================================================
   Design intent:
   - The canvas IS the window. Topbar above, footer below, and
     every other piece of UI (drawer, specs, bench, meters) floats
     on top of the canvas as overlays.
   - No stacked rows above/below the canvas. No dead brown space.
   - Overlays collapse or stay out of the way when not in use.
