Declutter the side and settings panels (review items a–f):
- New CollapsibleSection widget (slim navy header + coral rule + chevron).
- Inspector: Image features / Resolution rings / ROI are now collapsible and
start folded (ROI auto-expands when ROIs change); drop the Data-analysis and
Powder-calibration sections (they live in the hero buttons and settings dock).
- Settings dock: move Geometry to a shared section above the MX/AzInt toggle
(both communities need it); add Detector tilt (PONI rot1/rot2, deg) and
rename "Beam center" -> "Beam origin" with PONI/XDS tooltips; show the
space-group number and resolved Hermann–Mauguin symbol on one line; wrap
sections in accordions, anchored top with a bottom stretch so expanding one
does not shift the others.
- Toolbar: drop the redundant "Image number" label.
