Previously the horizontal-scroll fallback only applied at ≤640px; between
641px and 799px (tablet portrait, narrow desktop 2-col), the hero stayed
2-column so the wire-dump column could still be too narrow for the
~564px hex content, and overflow: hidden silently clipped the right side.
Lifting overflow-x: auto to all widths means: (a) any width where the
column is wider than the hex, content displays normally with no scroll;
(b) any width where the column is narrower, content becomes
horizontally-scrollable inside the dump. y stays hidden to keep the
typed-out animation's unrevealed lines clipped below the fold.
