chartRadarGridCircle#

// shadcn/ui "charts/radar-grid-circle" recipe — clean-room reimplementation.
//
// A single-series radar chart over a fully circular (ring) background grid
// while keeping the radial spoke lines, so the data polygon's straight
// hexagon silhouette contrasts against the round grid beneath it. Corner
// dots included by default. Hover tooltip shows the series color dot and
// "Desktop" label with the value, hiding only the month heading (hideLabel).
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
