/* ==========================================================================
   display-standardization fix — deck-15271 (2026-11-02)
   Whole-composition vertical centering for the flagged slides only
   (s3 asset, s4 gap, s6 system, s7 proof, s8 roadmap, s9 engagement).
   The complete inner content group (title/kicker/lead/body/cards/notes)
   centers between the global masthead and the dock. When content is
   taller than the stage, the auto margins resolve to zero and the slide
   keeps its natural reachable top-flow scrolling. Global chrome, copy,
   assets, typography and controls are unchanged. styles.css is untouched.
