/* V2-FOCUS-MODE-AB-002 — focus mode A/B styles. See focus-mode.js for spec.
   Variant A hard-collapses non-focus zones (display: none) and centers the
   focus target. Variant B mutes them (opacity 0.15 + grayscale) and gives
   the focus item a green left-border + soft tint. Transitions are 200ms. */
