chartRadarGrid#

// shadcn/ui "charts/radar-grid" recipe — clean-room reimplementation.
//
// The base member of the grid-variant family: a single-series radar chart
// over a circular (ring) background grid with the radial spoke lines
// suppressed — a cleaner "radar screen" look — plus a solid dot marker at
// each data vertex. The hover tooltip is minimal: just the raw value for
// the nearest month, no month-name heading.
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
