v0.14.6 layout repair
✓ Layout repaired: full-width single-column test bench, readable form controls, no narrow/shrunk side rail.
✓ Custom Row A/B now asks Qty + Container length clearly and drives all downstream container lists.
✓ Custom Row A/B quantities now actually generate the chosen row and flow through the whole page.
✓ Row B appears correctly in the coverage graphic and container counts.
✓ Dome preset + metres + feet stay synchronized both ways.
✓ Dome graphic scales to chosen length and prints the length inside.
✓ Long container layouts now use a vertical FRONT → REAR plan so 6+ containers never wrap into a misleading second row.
✓ Section 3 restores dynamic plan-view end-container diagrams for Inner corners / Between rows / Across outside.
✓ Section 5 uses square container ends; partial enclosure now runs from floor to apex and 100% means fully closed.
✓ Section 5 geometry responds to the selected end-container relationship and dome attachment reference.
✓ Personnel doors use mm + inches with sanity warnings; support heights now show explicit units and flag GAS reach at 1.65 m+.
✓ Four-corner support Ditto now copies the live Ground/Elevated state and typed height to all four corners.
✓ Per-container weight table follows all selected Row A / Row B / end containers.
✓ Regional wind follow-up remains directly beneath the wind requirement row.
