Order Book Histogram Demo

Three honest views of the same binned liquidity: Ladder (shows empty levels), Compact (skips empties but marks gaps), Window (fixed number of ticks around an anchor + overflow warnings).

View controls

Tick size changes the histogram bin width. Compact view marks gaps. Window view warns about off-screen liquidity.

UX guardrails: compact mode must show gaps, and window mode should disclose off-screen non-empty levels.
