Header: right-align EN|FR toggle in .hdr-in (top-right of page)

One CSS line: .lang-toggle{order:99;margin-left:auto}. Spec's literal order:99 alone
failed its own <=2px right-edge acceptance (gap 45.6-467.6px, 18/24 cases — order
reorders, .hdr-in is left-packed; geo-literal-order99.json), so margin-left:auto on
the toggle absorbs the free space; pill/logo untouched (spec-forbidden zone respected).

Battery: A1 gap=0px + rightmost + nothing-past-left in 24/24 (320/360/390/1280 x EN/FR
x intro/quiz/results); A2 header height unchanged 56/66px; A3 320px no overflow/wrap,
