orthographicSize is constant at 5.0 across 1920x1080 and 5120x1440 (visible
height 10.0, width 17.8 -> 35.6). The camera is already textbook Hor+ and needs
no patch - the entire ultrawide problem is HUD scaling.
CanvasScaler match=0.453 gave scaleFactor 1.948 (ballooned HUD); match=1 gives
1.333 with logical height exactly 1080 (the design height). Adds a live tuner
with independent match / scaleFactor / referenceResolution knobs to chase the
remaining text overlap.
