chartTooltipIndicatorLine#

// shadcn/ui "charts/tooltip" (indicator-line recipe) — clean-room
// reimplementation.
//
// Swaps the round color dot for a short vertical color bar/line indicator
// per series row. Upstream passes no labelFormatter, so the tooltip header
// shows the raw x-axis date string ("2024-07-16") — the axis tickFormatter's
// weekday label never reaches the tooltip — and every series value renders in
// a monospace / medium-weight / tabular-nums cell.
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
