Tab-strip MEMBERSHIP no longer exempts chromatic top/bottom stripes —
only a real selection marker does: aria-selected="true", aria-current
(any non-false value), or an active/current/selected class hint. A
stripe repeated on every tab in the group ([role=tab], .tabs items,
aria-selected="false" tabs) is decoration and flags as side-tab; the
selected tab's own underline — including the reserved-space
transparent-border pattern — stays legal. Applied consistently across
the element border path (isTabContextElement), the pseudo-element
stripe scan, and the inset box-shadow stripe scan.
Also replaces a stray NUL byte in the marquee scanner's dedupe key
that made tools treat checks.mjs as binary.
