/* ==========================================================
   Feature Alternating — Universal Module Styles
   Module: feature_alternating
   Tokens: uses --mt-* only (see /web/assets/css/00-tokens.css)
   No hardcoded colors. No template-specific selectors.
   Loaded once per page from /web/partials/feature_alternating.php
   via $GLOBALS['_feature_alternating_css_emitted'] guard.

   Layout strategy:
   - Desktop (≥768px): two-column row — text + visual. The
     .is-reverse modifier swaps which side each occupies, via
     explicit grid-column placement (no source-order change, so
     the reading order stays text-first for assistive tech).
   - Mobile (≤767px): single column — text above visual for
     EVERY row (reverse is neutralised) for a consistent,
     predictable scan order.

   Theme behaviour: surfaces read --mt-surface-card and
   --mt-surface-glass-border; light templates render flat cards,
   dark / glass templates redefine those tokens.
