Remove the stale body[data-active-view] .overview-strip { flex: 0 0 auto }
override from the three market-insight page stylesheets. Since the merged
header (B-147) moved the market tape into .app-header, this rule no longer
targets the old in-main overview strip and instead overrides the shared
shell rule (.app-header .overview-strip { flex: 1 0 auto }), which pushed the
header-actions icons off the right edge on auction, theme library and
popularity pages. Deleting the override lets the shared shell owner drive the
tape growth so the right-side icons sit flush like every other page.
Regenerate architecture-inventory.json line metrics for the CSS change.
