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,
FR logo ellipsis intact, elementFromPoint hit-tests lang buttons + Start over pass;
A4 FR/EN clicks switch lang+title+aria-pressed; A5 24 screenshots before/after; A6
engine 36 + i18n 48 + smoke 92 + ps-pension 70 green; A7 desktop pixdiff header-strip-
only, 0 px below header at every device, self-jitter bit-identical; A8 DEPLOY-OK,
origin marker=1 + byte-identical CSS, off-LAN troublebox 200+marker+rule OFFLAN-OK.

"""Desktop pixel-diff for the header lang-toggle move (spec acceptance 7).
|
|
|
|
Compares two screenshot dirs (intro/results, EN+FR) and proves the ONLY change is
|
|
inside the header strip: the diff bbox must sit entirely above `hdr_bottom` (masked),
|
|
and everything below the header must be bit-identical. Prints a self-jitter baseline
|
|
DIR_A vs DIR_A2 (same version captured twice) for the jitter-controlled comparison.

Usage: python3 audit/lang_right_pixdiff.py BEFORE AFTER HDR_BOTTOM
