chartBarMixed#

// shadcn/ui "chart-bar" (mixed recipe) — clean-room reimplementation.
//
// A horizontal single-series bar chart where every bar carries its own
// distinct accent color instead of sharing one uniform fill, so the chart
// reads like a small color-coded ranking; the axis labels double as the key
// (no separate legend).
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
