Four reports, three causes:
1. "Background plate has no code behind it" — the plate COLOUR and OPACITY controls were disabled
until the plate switch was on, which reads as dead controls. They are always settable now; the
switch is what decides whether a plate is drawn.
2. "Opacity doesn't work" — proven in the renderer test: 20% and 80% produce alphas of ~51 and ~204,
so the slider reaches the pixels. What was actually wrong was the box.
3. The strip's BOX was fixed at 56px while a wrapped strip renders taller — the frame was scaled
into the box and looked squashed/clipped. The source's width/height now follow the rendered
frame, and its Y follows from the edge.
4. "Simulate (dev) should override Show the scoreboard" — it does: the preview gate is
(_scoreboardEnabled || _scoreboardSimulate), so the dev toggle works even with the product
setting off.
Not changed: the strip is STATIC by design (all enabled facts always visible, wrap rather than
scroll). If scrolling is wanted after all, that is a presentation mode to add, not a fix.
