- Widen the tab sub-bar from a button-width pill to the full deck span (left/right edges of the main action bar), centering it on that span.
- Pack tabs at the left edge and Clear/Confirm + NET readout at the right edge, compressing gaps rather than button widths when the deck is narrow.
- Right-anchor the NET value (origin 1,0.5) and reserve its widest slot so growing totals never shift the label or overflow the bar.
- Extend SurfaceScene.shopAnchor to expose left/right edges for the sub-bar layout.
- Add sub-bar probe assertions in dev/shop-shot.mjs and unit tests in dev/shop-ui.test.mjs covering span, alignment, non-overlap, and NET math.
- Add carol character image and lava-land video assets.
