Educational visualization of a fee split -- a horizontal stacked bar with proportional segments, plus a label and Wei amount under each. Pairs with Web3.Ui.FeeBreakdown (which is the equivalent table view); use this one when you want a hero-tier "where does my fee go?" graphic on a marketing page or trade modal.

The bar segments are sized by basis points; total bps does not need to sum to 10000 (the bar is normalized to its own total).

Each Slice accepts an optional kind string -- emitted as a CSS class suffix (web3-feeflow__seg--<kind>) so the consumer can color the segments by recipient type without inline styles.
