What Changed — v4 → v5

For the architect & contractor: update AutoCAD from this page without re-reading the whole site. Click any drawing to zoom.
v5 fixes the blank/JS drawings (now static), corrects the flooring divider + floor plan, deepens W6 so the observation window sits flush, simplifies the window to a 2-pane unit, adds the HVAC ceiling access panel and the HDMI video tie, and switches the desk to a bought unit. The acoustic targets (RT60 / NC / STC) are unchanged.
